# History

SquirrelJME is an idea and execution that extends from previous ideas and
projects. The base idea extends from my desire to write an operating system to
run on systems, since such things have fascinated me.

# Old Projects (2011/01/15 - 2016/02/25)

These are old defunct projects which I have previously worked on.

I will say that it can take years before you can find a project you enjoy
working on and one that inspires you. Keep searching. Just be careful where
you step and do not take in more than you can handle.

## HandOS (2011/01/15 - 2011/01/22)

This was an attempt at creating an open source implementation of Palm OS.
Palm OS was not actively used much often and additionally existing emulators
for Palm OS are sub-par in that they were either old or were horribly out
of date. The goal of the project was to run m68k and ARM Palm OS applications
on the host system.

The project was fully structured and had all the default applications in place
as placeholders for when they were ready.

However, the project could not actually be compiled, it was mostly pretty much
just placeholders, some reference documentation, and notes. It did include
some tests which showed that threading was indeed possible on Palm OS like
modern systems.

## MPA Orange-Sapphire (2011/12/12 - 2011/12/13)

This was a very short project which never really took off. It was intended
to be an operating system written in a BASIC-like language. Obviously BASIC
is rather horrible compared to the languages of today.

## MPAYAOS (2012/02/20 - 2012/02/29)

Standing for __Yet Another Operating System__.

This was a short attempt at another operating system, it never really got
past the bootloader stage. It was written in C.

## HandNIX (2012/05/28 - 2012/05/29)

Standing for __Hand UNIX Environment__.

This was an attempt to make a UNIX-like environment for Palm OS so that I could
do development for my projects on Palm OS. It existed as a single C source code
file.

Only a few things were implemented. The major thing which was implemented was
a basic cooperative tasked system which was based on Palm OS's versions of
`setjmp` and `longjmp`. There also was a basic terminal emulator which did not
support any escape sequences.

Every POSIX command that existed on the system was referenced via a function
pointer and the intention was to have virtual files (via `#!`) which would
execute those internal commands when requested. The environment would have
started on the shell (`sh`) which would then be available to execute other
programs.

## HandOS 6.3 (2012/05/31 - 2012/08/17)

HandOS is a clone of Palm OS, however the main purpose of this project was to
implement the only released in a simulated environment: Palm OS Cobalt.

It was written in C and it required the Palm OS SDK for compilation.

I did not have headers for Palm OS 6, so I was writing the headers from
scratch.

## MPAPCOS (2012/09/30 - 2013/01/16)

Standing for __Posix Compatible Operating System__.

This was an attempt to write an operating system which was compatible with
POSIX:2008 and could run such programs. A C preprocessor was written and some
basic utilities were supported, but generally that was as far as it got.

## HandOS 5.6 (2013/01/23 - 2013/02/05)

This was another attempt at writing a Palm OS clone, it did not get very far.
There was basic project structure but not much else.

## MPAMSEK (2013/03/31 - 2013/04/14)

Standing for __Multi-System Emulation Kernel__.

This project was I believe to write an operating system which could run many
other operating systems in a very bare bones emulated environment to run as if
it were on native hardware. Basically, you would boot into a system and instead
of running an OS with an emulator running on it, the emulator would be
directly running on the hardware.

I only really got a basic system launch on PowerPC's Open Firmware. I was able
to print to the system's framebuffer console but not much else.

## MPAOSKP (2013/04/14 - 2013/05/15)

This project is based off MPAMSEK.

I am not too sure what the acronym stood for, very likely it stood for
__Operating System Kernel Project__.

I wrote a memory allocator but it never really got past the boot loader and
early kernel initialization stages.

PowerPC and x86 worked on Open Firmware.

I failed to get SPARC working, I could just not get the bootloader to run
properly and it usually ended up just crashing or not working at all. It may
have been related to register windows.

I thought about writing a C compiler but I gave up quickly and abandoned that
idea because that would be too much work with too little of a benefit.

## POSIX Environment for Palm OS (2013/07/25 - 2013/07/27)

This project was essentially similar to an earlier but was a POSIX environment
for Palm OS. By reverse engineering bits of Palm OS previously I determined
that some things were very possible. For Palm OS 5 I had pretty much a concept
background threading and server system. Basically a daemon would be launched
in the background which would keep the environment running. There would be a
connection made to the daemon with locks and semaphores. There would then be
a terminal interface which would show what was being output to the console.

There would be threads in the background running tasks. However to access the
server process a pointer would have to be remembered. This is where the
feature manager was used to keep a persistent handle in memory so the daemon
could be connected to. I determined that it was very important to be able to
switch programs outside of the environment.

For SquirrelJME on Palm OS, I have an idea to do something very similar so
that it runs in the background while other applications may be used.

## POSIX Environment for Palm OS (2014/10/12 - 2014/10/12)

This project never went past a few files and headers. The purpose of this
project was the same as the previous.

## k5 (2013/12/25 - 2014/04/25)

This project had 503 commits.

This is basically the start of my delving into Java virtual machines. It was
written in Java and was pretty bloated when it came to the compiler, using very
abstract concepts for compilation. It was to target Java SE but I am not too
sure which version it was for. Very likely it was Java 7 as Java 8 was released
shortly before this project ended.

I never really got past the JIT stage in the project. It was also quite massive
of a project.

Anything that was made for the documentation was written in LaTeX, which is
far less friendly compared to Markdown.

## k8/Squirrnix (2014/04/26 - 2016/02/25)

This is the direct predecessor to SquirrelJME. Utilities and classes in
SquirrelJME have been derived from this project. Generally if I find a class
which is missing in SquirrelJME I check this project and copy all the code
from there since the bulk of it is just placeholder.

This project had a massive number of commits: 9041.

It intended to implement the entirety of Java SE 8 with all of its profiles.
This was for the most part a very unrealistic goal. As with _k5_, it never
really got past the JIT stage. The massive requirements in place were
unrealistic. This project was doomed for failure even when it began but I was
a bit foolish to take up this task.

# SquirrelJME

## Starting Background

SquirrelJME stems from the following ideas:

I had a growing fascination with J2ME. I had an old cell phone which could run
J2ME applications. I would make a few concept projects but they did not last
long because programming for J2ME is quite horrible as it is very lacking when
it comes to Java. I did have the idea of writing a virtual machine that could
run J2ME applications so that I could use some again.

Another thing is that the write once and run anywhere aspect of Java pretty
much fascinated me also. The idea of writing a program once and having it
work pretty much everywhere was indeed interesting. I wanted to do this with
_k8_ but it was not really a feasible thing to do because it was so gigantic.

However, there was much frustration with my then current project _k8_. It was
gigantic and the number of classes to implement was essentially an impossible
mountain to cross. There was a growing sense of doubt that the project would
never get anywhere because it had unrealistic goals that would be impossible
for a single woman to obtain all by herself. I calculated that it could take
perhaps up to a decade to implement the core classes of Java SE 8. By a
decade's time, Java SE 8 would be obsolete and nobody would be using it anyway.
So this compounded a wasted effort. Additionally, being a third-party VM, there
would quite literally be very little interest in it, so it could not be for
fame. Basically it was too much and too ambitious of a project and sadly it
took two years to realize that.

Near the end of the project's life span I was a very depressed person, I felt
like the project was a complete waste of time and that life was rather
meaningless. I felt trapped working on the project with no escape. My life was
melting away into nothingness and worthlessness. I did not want to admit that
the project was a failure and would be going nowhere, I was naive.

In February of 2016 I watched Hack Summit 2016, it was pretty much the first
online conference which I have visited. It was really exciting. It did move
me a bit. However, I think the one talk which really moved me was the one by
_Sarah Allen_ (you can see her on YouTube here:
<https://www.youtube.com/watch?v=S1iYeThQO-g>). It really resonated with me.
It has really given me the light shining through my own fog to realize that my
own project was ruining my life. After that I decided that my own project was
not something I really wanted to do, that my ambitious goals were not even
caring for myself. I decided that I should care more about myself and that I
had to cut my project loose.

When that happened, I was still so very much interested in Java and having
write once and run anywhere, portability and virtual machines. I found Java to
be very awesome. I knew that _k8_ would never fit on the systems I would have
liked to target. I got the motivation to push Java as small as it can go. I
knew the gigantic size of _k8_ was too much, so I decided to switch to the
small scale. I remember my fascination with J2ME, I wanted to clone that
environment because I found it interesting. Java was seen as this gigantic
bloated monster that ate so much CPU and so much memory. But working with the
JVM so much made me realize how wrong it was. Java was in fact very small and
very light. J2ME was very light and very simplistic.

The first thing to do is determine has J2ME been updated ever? To my surprise
it actually was updated for Java 8. So this was quite something. Although it
was not really a microscopic Java 8 VM it was Java 7, which was good enough.
It added extra classes and was in general quite cool. JSR360, which is the
specification for Java ME 8 was proposed on October 2, 2012. The final release
was made on April 30, 2014. Java SE 8 being released on March 18, 2014. So
Java ME 8 came out very shortly after Java SE 8. However, with Android and iOS
being everywhere it never really stood a chance and Java ME 8 never really got
the chance to actually be anything.

I decided to study Java ME 8, to see if it was indeed viable. I took a quick
glance at it and then deeper dives into it. Java ME 8 imported quite a number
of things from Java SE 7. It basically was bringing it up to date with the
modern Java language rather than languishing in the past. It did remove some
things but, in the essence of compatibility those could still be brought in.
These removed things were stuff such as LCDUI, which were pretty much
nowhere. It took a bit to verify compatibility but the changes made do not have
an impact on backwards compatibility. As such this was a bonus.

One added bonus that I liked is that Java ME was so small compared to Java SE.
It is very tiny and extremely compact. Basically what is in the language is the
bare minimum sane choice. I will say that there are some errors and perhaps
some omissions but in general it has been rather good. The thought of Java SE
being implemented and the gigantic task I knew was impossible and the small
size of Java ME is actually is within reach. The small number of classes, up
around 512 classes for the standard makes it very reasonable. This estimated
512 classes is about half the size of Java SE 8's compact1 and does not include
things such as SQL. I really liked the fact that it gave you the minimum set
of classes and you could just bring your own classes in if you care about it.
Personally, I do not really care for SQL and stuff like CORBA because I do not
often use them at all.

## Naming and Mascot

The name _SquirrelJME_ comes from the fact that I personally find squirrels to
be very interesting and curious animals, not to mention that they are cute.
Where I used to live I would see squirrels all the time so they were quite
common, although where I live currently as of this writing I do not often see
squirrels.

Originally my plan for a mascot at least for _k5_ or _k8_ would be to have a
pink bunny rabbit in reference to _The Legend of Zelda: A Link To The Past_.
In this game there is a region that you can enter called the _Dark World_ where
every human who enters is transformed into an animal that reflects their
inner self. I then switched my idea to having the mascot be albino because
these animals are a bit more rare (since they are more easily predated in
nature because their bright white fur stands out). Then when _SquirrelJME_ has
come around I decided to keep the same mascot but make him a squirrel instead.
So the green tunic that Link wears is a reference to the Zelda series.

It was difficult finding a name for him, as such I initially decided on just
placeholder name for awhile. I thought about _Lexer_ but that was quite long
and slightly complicated, so I shorted it to _Lex_. It was nice and for the
most part the name stuck since I was happy with it. Therefor it was never
changed.

He was uploaded on 2016/05/07 to the repository.

He has subsequently been redrawn on 2018/10/19 by Kat Adam-MacEwen, where he
ended up very handsome. She is quite a wonderful artist.

The C based virtual machine **RatufaCoat** was named by _meepingsnesroms_ of
the Mu project. Ratufa being the sub-species of squirrels in southeast Asia.

## Gaining a Sister Project

On 2018/11/03 the developer of Mu, _meepingsnesroms_, wanted to become a sister
project of SquirrelJME, so this was very exciting! The link to her repository
is in the [readme](readme.mkd)! We will be cooperating mostly by word of mouth
by linking to each other's projects to hopefully gain interest in both of our
projects.

## The First Release

The first version of SquirrelJME was released along with Mu on
December 25, 2018. The repository had 10,571 commits. This version spent
two years in development.

This release was mostly just a demo to show that SquirrelJME exists and that
it is being worked on. It is very primitive and not much can be done with it.
From the release though there has been slowly increasing interest in the
project since there are not many emulators that support J2ME that exist and
are actively worked on.

## The Second Release

This is the currently being developed release. In 2019 without knowing the
calamity of the year 2020, I put down here:

> It is expected to be at most in development for two years and six months
> in development.

Naturally, as of this writing I am now at the two years and six months mark.
Having lost probably a year of productivity during 2020, this will definitely
mean this release gets pushed back.

### 2019

The history from January to June was taken from a note, although it was never
completed.

#### January

This is the month that was right after 0.2.0 was released. I started the
initial work on SummerCoat which has taken pretty much the entire year and
more to develop, it is a really complex system and it really shows. From
this run I had the initial SCRF compiler which would eventually be thrown
out and which would result in the current compiler that I wrote. I even
had a base project setup for RatufaCoat at the middle of January. I also
performed some refactoring of the compiler stuff as well making it cleaner
because it did get a bit messy. I did get method processing put in but that
was later split apart because wow it was complex. Also added a bunch of
new tests and implemented parts of the class library since they were needed
for the VM to function. I figured at this time that I should write a compiler
which is not all that optimized to keep it simpler, although today I do have
basic optimization in place. For CircleCI I put in JUnit reporting for the
tests that ran which has been around for awhile now. Also, for the tests that
run within the VM, the profiler snapshots are stored as well so that way
I can determine how fast stuff has been running accordingly. I defined an API
level for 0.4.0 but eventually later in the year I determined that the API
stuff is too complex, so I opted for the much simpler system call stuff.
I added system properties support for SpringCoat since I needed to enable or
disable debugging.

#### February

More work was done with SCRF. Added the ability to launch tasks with system
properties and such. SummerCoat VM went through a slight refactor as well.
Some of the stuff that I worked on this month have somewhat survived to the
end of the year such as the stack map stuff which worked well. I mostly just
implemented a ton of methods. Not much here this month.

#### March

This month was very rough for me because I had gotten laid off at the start of
the month and it was devastating to me. I pretty much still worked on this
project because it helped me get through the rough times and it also acted as
a resume for me as well. I was in and out of depression so I did not exactly
work on this every single day as I was job hunting as well.

One big thing I did was remove `tool-scrf` and put it in `tool-classfile` and
built it up from that. I know in 2020 I will be pretty much splitting that
back out and writing a far more streamlined compiler which hopefully is faster
and more efficient as well. This is where the `MinimizedClassFile` started
from so it has quite been around. It is still around and it has always been
improving from this point. SummerCoat had this class library kind of thing
that basically cached single classes and such I believe in memory. I know with
the compiler refactoring I brought stuff back in from SCRF since it still
worked just fine. For the class file stuff I implemented more things that were
missing such as the exception handler. I had all of the narrow and long stuff
which was a bit confusing, I know later this eventually was removed because it
was just impossible to handle while keeping things simpler. I know today that
everything is 32-bit for the most part. I also worked on the graphics stuff
too, which is interesting. This was even the advanced graphics stuff. This
graphics stuff needs to be refactored but that will get done eventually.
I also worked on Squirrel Quarrel when it was a Starcraft clone still, but now
today it is more of its own original game that I have planned. You could kind
of play it and command units I think and such. For graphics I added a
serializer so that it could be done by the host VM, being faster. I may do
that again for SummerCoat although it would be a bit more difficult. This
was also when I was more going twords <https://squirreljme.cc/> instead of my
standard domain that I use. I also am actually glad the complex type handling
was removed from SummerCoat. Even reference queues and such were their own
instructions, but now that is different.

#### April

At the start of this month I did some fixing of the class parser. I did lots
more compiler work. More library methods were implemented.

I renamed my Twitter and used my `MultiPhasicApps` handle for SquirrelJME
stuff, which actually helped me much.

I worked on the graphics stuff. Implemented some base record store stuff which
was nice. Refactored XPM and PNG image loading. Added a Null Audio system.

Lots of more compiler work.

Later in the month I completely refactored SummerCoat, it pretty much should
be the same as it is today just more worked on.

Also corrected testing stuff.

At the end of the month I put a bunch of work into the fonts too, I did so
much with them! I actually still need to finish the symbol fonts a bunch too.

Also kinda glad I do not have class IDs and such today as well.

#### May

More font stuff, yay!

This month I added the concept of BootRAM and this has actually simplified
things making things easier to load and such.

Added some more implementations to methods as well and HTTP support!

Also big refactor of the testing framework, which ended up going rather
nicely. I also added my first sorting algorithm which was ShellSort. However,
I guess now there is just block sort which does nothing? Oh wait no
there is ShellSort.

#### June

The notes stopped before June, so this and anything following was written
much later on at the end of 2020.

This month there was much work done on RatufaCoat and SummerCoat since they
are shared. The compiler has seen a number of changes as well. There was much
going back and forth, fixing things, and debugging things. A compiler and
virtual machine combination is very complex. Additionally, at the end of the
month SummerCoat got profiling output.

#### July

This was the month when I was hired for my second programming job, as such
from work there has been a great reduction in available time to work on
SquirrelJME. However money is important, I was a single month away before
I would have ran out which would not have been good.

At the start of the month I worked on Squirrel Quarrel a bit, I am assuming
at this point I was to make it a turn based strategy although it may have
been a real time strategy.

I did port RatufaCoat partially to Palm OS however it was not really
functional and there were a number of limitations. Other than that, there was
more minor work on SummerCoat/RatufaCoat. I decided it would be best to
split the constant pool into a static pool with a run-time pool, that is still
here to this day, however it is something that has simplified and reduced the
need to load everything at once.

However due to my new job, the month mostly just had progressed at the start.

#### August

Due to my job, there was little progress this month. I worked a bit on the
compiler, refactoring it and otherwise.

#### September

This month more work was done on the compiler, mostly with fixing bugs,
making it better, and other such things. I did do much more than what I did
the previous month however.

Unrelated to other things, I did put in support for a demo that requires a
proprietary JVM to run a game.

#### October

Worked more on SummerCoat and attempting to get it booting up and otherwise.
This would prove to be very difficult for me to do.

Otherwise, not much was done this month.

#### November

More work on SummerCoat and such, there were optimizations and fixes.

Most of this was done during the holidays where there were few days off.

#### December

Very much this was more work on SummerCoat. It was much work and I was
getting more and more burnt out from working on this.

### 2020

Virtually everyone who has spent some time in 2020 will know how rough the
year has been, there were no exceptions for myself.

#### January

I worked a bit more on SummerCoat but slowed down greatly, I decided to
implement some other classes and such.

#### February

This was a difficult month... my close friend Emily passed away at the start
of the month. I was devastated and was broken from it, I remember being at
work and hearing the news and I sunk in my chair. I remember going outside
and sitting on the small bench employees went to for their break. I broke
down and cried. I remember calling my fiance and asking her to pick me up
early from work. I knew she could tell that something was very wrong. I
stuttered to tell her. My fiance comforted me so much. I still think of Emily
often and I feel an emptiness inside of me when I do so. Typing this is
difficult, but... I will remember her always. She was a close friend to me
and we would talk so often. I do know that she was very thankful to have me
as a friend. I hope that she is resting in peace.

Being devastated, I did my best to distract myself.

I remember just sitting down and was thinking how many months have gone by
working on SummerCoat and such, being in an endless loop. I decided to change
how I was doing SquirrelJME to use more modern development tools. I had always
previously wrote it using a basic terminal and a basic text editor. I decided
to make the switch to IntelliJ, which I can definitely say made development
much easier. The first most important thing to do was to setup the Gradle
build system, which I was doing. I never went with Gradle in 2016 because
it was too limited, however in 2020 it has gone far enough in development to
where it could work well with SquirrelJME. I did major cleaning up and
otherwise. Organizing things and setting up testing like I had before. I 
setup a basic JNI wrapper for native calls since I need to do SquirrelJME
things in Java SE to run them properly. I worked a bunch on the dependency
system and otherwise, building a SquirrelJME plugin that could do everything
I needed. I additionally started development in branches so I could do
multiple things back and forth, this would help at times with ADHD.

#### March

SquirrelJME for the time was keeping me distracted much, my fiance was there
for me as well. At the start of this month I married her, so from now on she
is my wife. I know she has helped me get through this year so many times and
I love her very much. We married the day before lockdown, we were very lucky.

For SquirrelJME, I continued on the Gradle work. By the second I had already
merged in all of Gradle changes. It did feel good the direction this was going
and it was the start of taking a new path. I know there were many thoughts to
when I started SquirrelJME, how it was basically started from the realization
that I was going nowhere with my SummerCoat work. So that was shelved for
awhile.

I started work on bringing up SpringCoat. This would involve a large number
of refactors and otherwise, to improve the old virtual machine I was intending
to originally remove. I decided it would be best to keep SpringCoat because
it is an additional vector into making sure things are operating. At least
with the optimizations I have done it much quicker. I effectively continued
it throughout the month. I made much progress. By the end of the month much
was done but there was still a way to go.

#### April

This month started with continuing the refactoring and upbringing of
SpringCoat. For the most part it was continuing but at a slower pace.

#### May

For the most part, I continued work on bringing up SpringCoat. However after
about two months of working on it I realized that I was falling into the same
pit as before with SummerCoat. So I decided to backpedal and start a new
branch which was effectively cherry picking what I did. This was the second
half of the month.

I had previously rewritten TAC, which that was cherry picked. I picked up
some other things, but I suppose a bunch of it was dropped. This is okay
though. This cherry picking was merged into `trunk`.

I additionally at the end of the month did a bunch of syntax and miscellaneous
cleanup, this was a nice way to organize.

At the very end of the month, I decided that I needed to do this another way.
So SpringCoat was very high-level and SummerCoat was very low-level, but it
was difficult to bridge these together. So I decided on an idea of having a
Mid-Level Emulation (MLE) which would bridge the gap. This is still around
to the time of writing, so it has definitely been a good decision.

#### June

The first half of the month, little progress was made as I was mostly thinking
about the best way to do things. It was thinking from nothing again, but I
eventually figured it out. I did so some refactorings and such naturally.

However the second half of the month, I did much more work. I improved testing.
I wrote new APIs for SpringCoat and put these on the emulation layer. I
decided that it would be best if SpringCoat not do any `Assembly` stuff since
that was complicated and I did not want to handle that for now. I did end
up doing much work on SpringCoat as well. The speed increased more and it
was much better.

At the very end of the month, I worked on utilities to replace the old
shell scripts so that I could develop purely on Windows rather than a Linux
VM.

I continued to do much more work on Mid-Level SpringCoat and eventually merged
everything in accordingly! It was a very nice feeling.

#### July

This month was my birthday month but also I started work on Mid-Level LCDUI
Refactoring and work on access control. Also the ability to launch tasks
was added as well in the access control branch. Otherwise the Mid-Level LCDUI
work is basically a complete refactoring of the LCDUI code. Before I had
something that was too high and native while another that just used the
framebuffer. So I decided to take a path that would allow both. For now it is
based on Swing but it is very possible for it to be backed on a Framebuffer.
Naturally for what is running on RetroArch will be using the framebuffer along
with any system that lacks native widgets. However, for the systems that
support it, it will effectively reduce the work that is needed to be done to
make everything consistent to make it feel like it would be for that
operating system.

The access control stuff carried on a bit and I decided I could really use
what I wrote via the tasks, so I forked off that branch and merged that into
`trunk`. I then merged `trunk` into the other branch. So this way whatever
work I done could be used. Since access control is not too important. But
otherwise, I made improvements there.

Near the end of the month I started on a slight refactor to RatufaCoat
and switching it to CMake. Using CLion which is a very nice IDE, it should
make it easier to work on it. It took about two days to do all of this so
it was a really short-lived branch. But other than that, it did pave the way
for refactoring of RatufaCoat. Regardless though I took a short break on
the LCDUI stuff since I have been working on it for awhile.

On the 28th, I spent a day working on a user guide and a FAQ to answer some
questions. This gets synced to GitHub accordingly. Something I feel is
important since people tend to ask a bunch of questions about this.

#### August

This month I continued work on the LCDUI refactoring. I also started a new
branch for refactoring the handling of the many virtual machines
and the means for testing it. This work has been very helpful as I still use
it and it is helping me progress and making sure everything is tested.

I also additionally started work on refactoring RatufaCoat which is ongoing
but that is expected as I wanted to start some of it through interest despite
SummerCoat itself not being ready. Of course once SummerCoat is ready I will
likely work on this.

But majorly the month was spent on the build refactoring.

#### September

This continues the build refactoring and by the second week of the month I
merged it in. It has been very beneficial. But from doing this and taking a
break from the LCDUI work, I continued work on that. Pretty much the entire
rest of the month was working on this.

#### October

This month continued the LCDUI work. At the start of the month I removed a
bunch of the old code as it was no longer needed. Other than the LCDUI work
I did some additional changes to the CI/CD pipelines. Progress on the LCDUI
was scattered though and was generally slow to progress.

#### November

This month at the start was more of the same, working on the LCDUI. However
after about half the month the branch was merged in. It was not 100% however
it was at a level I was good with and I did not want to drag it on for more.
So I took what I had and merged it in.

By the end of the month I started work on building the SummerCoat ROM, this
was a combined image file and otherwise that would be needed by SummerCoat.
This was mostly just to get the tasks running but not a ROM that could actually
be ran. However I did merge this in.

After that, at the very end of the month I started working on Mid-Level
SummerCoat. Like MLE SpringCoat, this was a refactor and simplification of
SummerCoat, so I could get things running again.

#### December

This month I continued work on Mid-Level SummerCoat, although work has been
scattered. I have been making very good progress on this however, since
whatever progress I make is good.

Other than that, at the end of the month I started work on doing the completion
counts which would be used to determine how far I am with standard API
implementations and otherwise.

Near the very end of the month, publishing was added to Maven Local, BinTray,
and OSS SonaType. This would allow documentation to potentially be downloaded
or browser, but will mean that SquirrelJME can be consumed by others. There
were additional fixes to task launching.

### 2021

To be written...

#### January

I finished up the end of the year fixes on launching on the first day of
the month.

I essentially spent this month working on mostly SummerCoat, would say good
progress was made on this.

There were minor fixes to the RetroArch build.

I planted roots for better graphics handling that would allow for more
accuracy and acceleration.

#### February

I started the month working on SummerCoat, but also decided I wanted to work
on RatufaCoat as well. So half of the month was dedicated to each. Before
this point, the RatufaCoat work was based on `trunk` but I then switched it
to be based on the SummerCoat WIP since there would be no other way to
reliably work on it. I also did major CMake work on this branch, since it is
a very nice build system.

#### March

I continued work on the RatufaCoat branch, making good progress and cleaning
up accordingly. 

I discovered that there is an issue in SummerCoat, but it was disparaging to
find and fix. There was not much motivation to do so. I needed a debugger
first and foremost.

I started work on shiny new JDWP support, which would help with finding issues
and otherwise.

I did attempt to cherry-pick the improved LCDUI event handling but that
failed, however that eventually got brough in by a future cherry-picking in
July.

#### April

This was a big month for the JDWP support, I finished the debugging support
for SpringCoat which allowed me to find potential issues and otherwise.
Being able to debug in IntelliJ was very useful as well, although it is not
the only supported debugger (Eclipse and JDB are supported).

Otherwise I worked on support for software `float`.

#### May

Base64 had some fixes and improvements, along with the addition of encoding
to Base64.

A class dumper was added so that I could debug the SummerCoat compilation
issues that existed. There were bug fixes centered around this. From this
a discovery was made that SummerCoat's handling of stack exchanges was
incorrect. However, there was not much motivation to fix this, it just
made a bad feeling in me.

I made a WIP branch for an SDK, which will be a modern way to develop for
SquirrelJME and J2ME.

#### June

Not much was done this month other than the detection of _i-Mode_ titles in
the launcher. Previously I planned to have a separate launcher that did this
but I decided against that since it would be better if it were all included
at once. This should make it easier to use this software. It does though
require the two files that are needed. In light of needing these additional
support files, I improved support for non-JARs in the library pickups.

Other than this, there was minor work and optimizations on SummerCoat.

Fixes were made to LCDUI and the floating-point functions were corrected.

At the very end of the month, one of my closest friends Near passed away. I
will miss you lots, you helped me immensely, you will be missed always. It
was an honor to be your friend.

#### July

I decided this month to celebrate my birthday for the first time in a very
long time, since it has never really been a day I wanted to celebrate ever.
I had a wonderful birthday with my wife, who makes me very happy. I decided
to add an extra candle for both Emily and Near, since they never really
were able to celebrate their own birthdays. I wanted to do this if at least
in spirit.

Additionally, at work I was placed on an important project, which at times I
would be working overtime. So I am doing my best to maintain a work/life
balance.

By the end of the month I very heavily realized how long the SummerCoat branch
has been going on for, since November 2020. I could not find the heart or
feeling to work on anything in SquirrelJME because this branch was just too
big, I made unrelated changes in it that were very important. Probably one of
the biggest things I have done this month is cherry-picked into `trunk`
from this branch.

These cherry pickings include:
 * All the various Gradle changes and fixes.
 * Base64 fixes.
 * Fixed event handling for LCDUI.
 * LCDUI form related functions.
 * MLE changes that I want to keep but both affect SpringCoat and SummerCoat.
 * Fixes to SpringCoat.
 * Optimized and corrected sorting algorithms (ShellSort).
 * Software math support for `float` and `long`. 
 * Additional tests which caused compilation issues within SummerCoat.
 * Task improvements.

Additionally, the WIP branches for BuildVM and RatufaCoat had an improvement
for the automated tests. The list of lists are now dynamically generated
rather than having to copy them into two separate locations, this will make
it easier to use and otherwise.

The long-standing SummerCoat issue was fixed and corrected this month with
an unoptimized, but working, solution.
