Resolves#3075
TODO before merge:
- [x] Properly draw non-korean strings while in korean mode (language
selection)
- [x] Check jak 3
- [x] Translation scaffolding (allow korean characters, add to Crowdin,
fix japanese locale, etc)
- [x] Check translation of text lines
- [x] Check translation of subtitle lines
- [x] Cleanup PR / some performance optimization (it's take a bit too
long to build the text and it shouldn't since the information is in a
giant lookup table)
- [x] Wait until release is cut
I confirmed the font textures are identical between Jak 2 and Jak 3, so
thank god for that.
Some examples of converting the korean encoding to utf-8. These show off
all scenarios, pure korean / korean with ascii and japanese / korean
with replacements (flags):

And it working in game. `Input Options` is a custom not-yet-translated
string. It now shows up properly instead of a disgusting block of
glyphs, and all the original strings are hopefully the same
semantically!:

Quite the challenge. The crux of the problem is -- Naughty Dog came up
with their own encoding for representing korean syllable blocks, and
that source information is lost so it has to be reverse engineered.
Instead of trying to figure out their encoding from the text -- I went
at it from the angle of just "how do i draw every single korean
character using their glyph set".
One might think this is way too time consuming but it's important to
remember:
- Korean letters are designed to be composable from a relatively small
number of glyphs (more on this later)
- Someone at naughty dog did basically this exact process
- There is no other way! While there are loose patterns, there isn't an
overarching rhyme or reason, they just picked the right glyph for the
writing context (more on this later). And there are even situations
where there IS NO good looking glyph, or the one ND chose looks awful
and unreadable (we could technically fix this by adjusting the
positioning of the glyphs but....no more)!
Information on their encoding that gets passed to `convert-korean-text`:
- It's a raw stream of bytes
- It can contain normal font letters
- Every syllable block begins with: `0x04 <num_glyphs> <...the glyph
bytes...>`
- DO NOT confuse `num_glyphs` with num jamo, because some glyphs can
have multiple jamo!
- Every section of normal text starts with `0x03`. For example a space
would be `0x03 0x20`
- There are a very select few number of jamo glyphs on a secondary
texture page, these glyph bytes are preceeded with a `0x05`. These jamo
are a variant of some of the final vowels, moving them as low down as
possible.
Crash course on korean writing:
- Nice resource as this is basically what we are doing -
https://glyphsapp.com/learn/creating-a-hangeul-font
- Korean syllable blocks have either 2 or 3 jamo. Jamo are basically
letters and are the individual pieces that make up the syllable blocks.
- The jamo are split up into "initial", "medial" and "final" categories.
Within the "medial" category there are obvious visual variants:
- Horizontal
- Vertical
- Combination (horizontal + a vertical)
- These jamo are laid out in 6 main pre-defined "orientations":
- initial + vertical medial
- initial + horizontal medial
- initial + combination
- initial + vertical medial + final
- initial + horizontal medial + final
- initial + combination + final
- Sometimes, for stylistic reasons, jamo will be written in different
ways (ie. if there is nothing below a vertical vowel will be extended).
- Annoying, and ND's glyph set supports this stylistic choice!
- There are some combination of jamo that are never used, and some that
are only used for a single word in the entire language!
With all that in mind, my basic process was:
- Scan the game's entire corpus of korean text, that includes subtitles.
It's very easy to look at the font texture's glyphs and assign them to
their respective jamo
- This let me construct a mapping and see which glyphs were used under
which context
- I then shoved this information into a 2-D matrix in excel, and created
an in-game tool to check every single jamo permutation to fill in the
gaps / change them if naughty dogs was bad. Most of the time, ND's
encoding was fine.

anything in red is an addition / modification on my part.
- This was the most lengthy part but not as long as you may think, you
can do a lot of pruning. For example if you are checking a 3-jamo
variant (the ones with the most permutations) and you've verified that
the medial jamo is as far up vertically as it can be, and you are using
the lowest final jamo that are available -- there is nothing to check or
improve -- for better or worse! So those end up being the permutations
between the initial and medial instead of a three-way permutation
nightmare.
- Also, while it is a 2d matrix, there's a lot of pruning even within
that. For example, for the first 3 orientations, you dont have to care
about final vowels at all.
- At the end, I'm left with a lookup table that I can use the encode the
best looking korean syllable blocks possible given the context of the
jamo combination.
Fixes#3909
Long standing issue in Jak 2's subtitles, it's actually kinda incredible
that finnish didn't run into this problem. Later in this code it
accesses the subtitle based on the language-id, and finnish is always
out of bounds -- but it never caused a catastrophic issue.
Polish on the otherhand is much more out of bounds and always causes an
access violation / crash.
Jak 2's subtitle code has no fallback (ie. use english if not
translated) for cutscenes, since they are not defined in the base file
like in Jak 1. This means that an untranslated language will render no
subtitles during cutscenes. Translations are welcome!.
Tested a cutscene in:
- english
- italian (base game with subtitles)
- finnish (new language, actually is translated)
- polish (new language, not translated)
Major change to how `deftype` shows up in our code:
- the decompiler will no longer emit the `offset-assert`,
`method-count-assert`, `size-assert` and `flag-assert` parameters. There
are extremely few cases where having this in the decompiled code is
helpful, as the types there come from `all-types` which already has
those parameters. This also doesn't break type consistency because:
- the asserts aren't compared.
- the first step of the test uses `all-types`, which has the asserts,
which will throw an error if they're bad.
- the decompiler won't emit the `heap-base` parameter unless necessary
now.
- the decompiler will try its hardest to turn a fixed-offset field into
an `overlay-at` field. It falls back to the old offset if all else
fails.
- `overlay-at` now supports field "dereferencing" to specify the offset
that's within a field that's a structure, e.g.:
```lisp
(deftype foobar (structure)
((vec vector :inline)
(flags int32 :overlay-at (-> vec w))
)
)
```
in this structure, the offset of `flags` will be 12 because that is the
final offset of `vec`'s `w` field within this structure.
- **removed ID from all method declarations.** IDs are only ever
automatically assigned now. Fixes#3068.
- added an `:overlay` parameter to method declarations, in order to
declare a new method that goes on top of a previously-defined method.
Syntax is `:overlay <method-name>`. Please do not ever use this.
- added `state-methods` list parameter. This lets you quickly specify a
list of states to be put in the method table. Same syntax as the
`states` list parameter. The decompiler will try to put as many states
in this as it can without messing with the method ID order.
Also changes `defmethod` to make the first type definition (before the
arguments) optional. The type can now be inferred from the first
argument. Fixes#3093.

This renames the method object in `defmethod`s to `this` and adds
detection for the `set-time!` and `time-elapsed?` macros.
Definitely my biggest PR yet...
Previously, `object` and `none` were both top-level types. This made
decompilation rather messy as they have no LCA and resulted in a lot of
variables coming out as type `none` which is very very wrong and
additionally there were plenty of casts to `object`. This changes it so
`none` becomes a child of `object` (it is still represented by
`NullType` which remains unusable in compilation).
This change makes `object` the sole top-level type, and the type that
can represent *any* GOAL object. I believe this matches the original
GOAL built-in type structure. A function that has a return type of
`object` can now return an integer or a `none` at the same time.
However, keep in mind that the return value of `(none)` is still
undefined, just as before. This also makes a cast to `object`
meaningless in 90% of the situations it showed up in (as every single
thing is already an `object`) and the decompiler will no longer emit
them. Casts to `none` are also reduced. Yay!
Additionally, state handlers also don't get the final `(none)` printed
out anymore. The return type of a state handler is completely
meaningless outside the event handler (which is return type `object`
anyway) so there are no limitations on what the last form needs to be. I
did this instead of making them return `object` to trick the decompiler
into not trying to output a variable to be used as a return value
(internally, in the decompiler they still have return type `none`, but
they have `object` elsewhere).
Fixes#1703Fixes#830Fixes#928
This PR adds detection of the `launch-particles` and `seconds-per-frame`
macros to the decompiler, removing a lot of bloat and hiding many
process register uses.
I also added `og:preserve-this` comments to as many manual patches and
comments as I could, which will soon be used in conjunction with CI to
hopefully catch any regressions in future big decomp update PRs.
I have some concerns about the `launch-particles` macro (more details in
`sparticle-launcher.gc`) , but thus far, I have not seen anything break
yet.

The main thing that was done here was to slightly modify the new
subtitle-v2 JSON schema to be more similar to the existing one so that
it can properly be used in Crowdin.
Draft while I double-check the diff myself
Along the way the following was also done (among other things):
- got rid of as much duplication as was feasible in the serialization
and editor code
- separated the text serialization code from the subtitle code for
better organization
- simplified "base language" in the editor. The new subtitle format has
built-in support for defining a base language so the editor doesn't have
to be used as a crutch. Also, cutscenes only defined in the base come
first in the list now as that is generally the order you'd work from
(what you havn't done first)
- got rid of the GOAL subtitle format code completely
- switched jak 2 text translations to the JSON format as well
- found a few mistakes in the jak 1 subtitle metadata files
- added a couple minor features to the editor
- consolidate and removed complexity, ie. recently all jak 1 hints were
forced to the `named` type, so I got rid of the two types as there isn't
a need anymore.
- removed subtitle editor groups for jak 1, the only reason they existed
was so when the GOAL file was manually written out they were somewhat
organized, the editor has a decent filter control, there's no need for
them.
- removed the GOAL -> JSON python script helper, it's been a month or so
and no one has come forward with existing translations that they need
help with migrating. If they do need it, the script will be in the git
history.
I did some reasonably through testing in Jak1/Jak 2 and everything
seemed to work. But more testing is always a good idea.

Adds support for adding custom subtitles to Jak 2 audio. Comes with a
new editor for the new system and format. Compared to the Jak 1 system,
this is much simpler to make an editor for.
Comes with a few subtitles already made as an example.
Cutscenes are not officially supported but you can technically subtitle
those with editor, so please don't right now.
This new system supports multiple subtitles playing at once (even from a
single source!) and will smartly push the subtitles up if there's a
message already playing:
Unlike in Jak 1, it will not hide the bottom HUD when subtitles are
active:
Sadly this leaves us with not much space for the subtitle region (and
the subtitles are shrunk when the minimap is enabled) but when you have
guards and citizens talking all the time, hiding the HUD every time
anyone spoke would get really frustrating.
The subtitle speaker is also color-coded now, because I thought that
would be fun to do.
TODO:
- [x] proper cutscene support.
- [x] merge mode for cutscenes so we don't have to rewrite the script?

Also fixed an original game bug in `loader.gc` on a method that's called
quite often, though I have no clue what erroneous behavior it could have
even caused.
Adds sprite distort, fixes buggy sprite rendering in progress, adds
scissoring support (used in various scrolling menus) and a very basic
implementation of `blit-displays`. This is enough to make the fade
effect in the progress menu work, along with all the menus working
properly without needing to use the REPL. This does not make screen
flipping and the filter when failing a mission work.
Added support in the decompiler for detecting `dma-buffer-add-gs-set`
and `dma-buffer-add-gs-set-flusha` and updated all of the Jak 2 code to
use it. Readability improved!
Fixes decompiler issue with `with-dma-buffer-add-bucket` not inlining
forms which broke syntax. Fixes store error warnings showing up for
non-existent stores, there is now a dedicated pass for this at the end.
I started work on making `BITBLTBUF` stuff work in the DirectRenderer,
but stopped for now because it wasn't strictly necessary. It will still
assert like before.
There are *a lot* of file changes and while I have carefully gone
through every gsrc change to fix up manual patches, there might still be
spots that I missed.
I didn't actually visually notice much of a difference with these hacks
unlike in Jak 1, but I also avoided checking the missions thoroughly
since the game crashes very often right now.
Adds the `pckernel` system to Jak 2, allowing you to do the PC-specific
things that Jak 1 lets you do like change game resolution, etc.
In other to reduce the amount of code duplication for something that
we're gonna be changing a lot over time, I split it into a few more code
files. In this new system, `pckernel-h.gc`, `pckernel-common.gc`
(previously `pckernel.gc`) and `pc-debug-common.gc` are the files that
should be shared across all games (I hacked the Jak 2 project to pull
these files from the Jak 1 folder), while `pckernel-impl.gc`,
`pckernel.gc` and `pc-debug-methods.gc` are their respective
game-specific counterparts that should be loaded after. I'm not fully
happy with this, I think it's slightly messy, but it cleanly separates
code that should be game-specific and not accidentally copied around and
code that should be the same for all games anyway.
- worked around audio code for gungame, the tutorials now function
- auto-exit cutscenes upon entry. This doesn't always work nicely (i
didnt want to cause any side-effects due to messing with load states)
but it atleast stops jak from being stuck forever waiting for the
cutscene to load
A big one...
I figure even if we would like to change the way the particle/scene code
is output -- it'd be easier to find patterns with it all decompiled.
I've updated my script so it can easily be used to mass update these
files:
```bash
task update-gsrc-glob GLOB="**/*-part*.gc"
```
> for example will update gsrc files with `part` in their name -- if
they are in ref tests (so uncompleted ones aren't touched)
I found a few issues along the way that I'll have to make issues for
soon.
* wip
* getting stuff set up so we can actually run test cases
* better handle block entry stuff
* types2 working on gstring
* comments
* math ref working
* up to first stack stuff
* stack fixes
* bounding box
* math stuff is working
* float fixes
* temp debug for (method 9 profile-array)
* stupid stupid bug
* debugging
* everything is broken
* some amount of type stuff works
* bitfield
* texture bitfields not working
* temp
* types
* more stuff
* type check
* temp
* float related fixes for light and res problems
* revisit broken files, fix bugs
