I accidentally built a tool to let you search a binary file in UTF-16, and the gimmick is that it searches in UTF-16 Big Endian and Little Endian at the same time.
Annoyingly, this is not what the tool I was trying to make is supposed to do, so it's slightly weird that I just did that.

@nycki I am flattered by the comparison.

after approximately an hour and 15 minutes my program finally runs, and successfully does what I wanted it for:
To locate the word "Thailand" in the Katamari Damacy PS2 ISO.
Foone🏳️⚧️
It's at decimal offset 1880088 if you were wondering.
Foone🏳️⚧️
Damn it, that's not it!
Even with that overwritten (as Shailand), the King of All Cosmos still says "Thailand"
Foone🏳️⚧️
@ada tthere was only one!
unless there's a bug in my search code, which... hang on.
*neptunyl⁷-hydroxide :neptune: :neobot_cofe:
@foone@digipres.club stupid question: did you replace all instances or only one (or was there only one?)
Foone🏳️⚧️
@ada I think there was, but I fixed it, and it doesn't matter.
Viss
@foone oh shit are you hacking on katamari damacy? i love that game! the soundtrack is fucking excellent
Foone🏳️⚧️
@Viss ayup
Foone🏳️⚧️
@ada pretty sure it's compressed, but there was a bug that meant I didn't find it. I may have fixed that!
*neptunyl⁷-hydroxide :neptune: :neobot_cofe:
@foone@digipres.club If i were to make an educated guess, it's probably in some compressed chunk and you replaced the fallback string.
Or they are actually using utf-32 like funny people.
*neptunyl⁷-hydroxide :neptune: :neobot_cofe:
@foone@digipres.club surely they wouldn't be using utf-32
Foone🏳️⚧️
Nothing. Either it's encoded in a different way than the one I'm using, or it's saying "Thailand" inside a compressed object I'm not decompressing.
Or both.
Foone🏳️⚧️
ugh. do I write a half-assed relative searcher or do I go find the decompression code and apply it elsewhere... or maybe I get the debugger out and try to learn MIPS assembly at 11pm?
Foone🏳️⚧️
there are many options! all bad!
Foone🏳️⚧️
@shac I did do it when I was a baby! in college!
shac ron ₪
@foone MIPS assembly is so easy a baby could do it

I found a font through texture-dumping, but it's missing some characters that show up in the text, so... I think this is a different font.
Foone🏳️⚧️
mmm, nope found another piece of it. It's just a font engine that uses multiple font sources
Foone🏳️⚧️
I bet they've got some rich-text composing system where their text is saved as like (font1,'T'),(font2,'h'),(font2,'a'),(font2,'i'),... instead of 'Thailand'.
Foone🏳️⚧️
you know that "Oh god, he's going for the jukebox!" meme?
She's launched ghidra.
Foone🏳️⚧️
and I wrote a half-assed relative searcher. some possibilities show up in RAM
Foone🏳️⚧️
@gsuberland I've thought about it!
I haven't reinstalled Cheat Engine onto my new system yet, because the whole semi-free thing put me off, though
Graham Sutherland / Polynomial
@foone I should create a PR for that for Cheat Engine. like the pattern search but for value deltas.
Foone🏳️⚧️
meh patching all of them in ram, before the line shows up? no change.
Foone🏳️⚧️
unless these fuckers are keeping text in texture ram, which I guess is possible
Foone🏳️⚧️
@gsuberland nah, I'd see it in the texture dump. There's definitely a font engine here, I just have no idea where any of its source text is
Graham Sutherland / Polynomial
@foone raster image, maybe?

"v" is a python bytestring. Can you spot the typo in this code?
if v=='b?':

read every other letter. I think I found it.
Foone🏳️⚧️
my code is now dynamically composing regexes so it can search multiple gigabytes of PS2 debris. It is slow and unknowable
Foone🏳️⚧️
@lizzy python's.

I have found some parts of the script in memory, but it doesn't seem to do anything i I change them (I'm changing them while viewing the previous line).
So I'm guessing it's per-calculating texture coordinates early? it doesn't seem to revert my memory changes like it's overwriting them by reloading the source data
Foone🏳️⚧️
@lizzy ahh. Any alternatives I could drop in?

here's a handy trick for figure out what code writes the text in the game, if you can only find matches after it's been decoded:
save state before it appears. play forward until it does, search the text to find the memory address, then load state, set a memory watch on that address, then hit play
Foone🏳️⚧️
WHO DO YOU THINK YOU ARE I AM?
Foone🏳️⚧️
@darkling good point

@foone Lost opportunity: Ohailand!
Foone🏳️⚧️
the game loads this specific line when you hit start on the title screen.
wow.!
Foone🏳️⚧️
it's a line at the start of the first level you can play, but the title screen doesn't load you there, it loads you on the home planet, then you have to travel to earth and select the level. but it's been loaded the whole time!
Foone🏳️⚧️
note to self: DO NOT CHANGE THAT BYTE
Foone🏳️⚧️
I think this is just the whole script:
[700b][1013][5005][5006][1011][100c][3001][500a]Sawa dee Krab[0406][f000][f000]Have you ever been to Thailand[0405][f000][f000]It[0506]s all about kicking in Muay Thai[0503][f000]You know[0405] Muay Thai[0503] Kickboxing[0503][f000]Oh[0502] yes[0503][100a][100a][100a][100a][100a][100a] Almost forgot[0503][f000]Hurry up and make a big star

ugh. I think the decompression is multithreaded. that makes this way more annoying

I have 3238 screenshots of Katamari Damacy. I hope this is enough
