maybe I'd be better at getting back into my reverse engineering projects if getting back into them didn't involve first figuring out which of the 13 Ghidra versions I have installed is for that project

clayote (clayote@peoplemaking.games)'s status on Sunday, 01-Sep-2024 16:10:16 JST clayote @foone The relation between gender and a floppy disk is between gender and that floppy disk.

Foone🏳️⚧️ (foone@digipres.club)'s status on Sunday, 01-Sep-2024 16:10:18 JST Foone🏳️⚧️ I think these guys wrote their scripting language so that array types have a declared length, but then neglected to actually tell the script executor about that. it doesn't seem to save that information anywhere or compare it to anything

Foone🏳️⚧️ (foone@digipres.club)'s status on Sunday, 01-Sep-2024 16:10:18 JST Foone🏳️⚧️ the worst thing about this particular scripting language is that it's compiled to bytecode, but they also have a debug file that includes all the information removed by byte-compiling. So I have variable names and comments and such, right?
but it's in a separate binary format that I can't load. So it's tempting but also useless

Foone🏳️⚧️ (foone@digipres.club)'s status on Sunday, 01-Sep-2024 16:10:20 JST Foone🏳️⚧️ oh god. I thought I'd fill out the resolveTypes function of module loading but it turns out it's a five-pass loader that loads data in place

Foone🏳️⚧️ (foone@digipres.club)'s status on Sunday, 01-Sep-2024 16:10:21 JST Foone🏳️⚧️ huh. this game has a "SILENCE LOADING ERRORS" flag. there's no way to turn it on, so loading errors will always be reported.
normally games have a verbose/debug flag that devs turn on, not a "be quiet" flag that never gets turned on

Foone🏳️⚧️ (foone@digipres.club)'s status on Sunday, 01-Sep-2024 16:10:22 JST Foone🏳️⚧️ but because this is all done in an in-place loading style, it's really a pain to understand, so I've not yet been able to write a disassembler

Foone🏳️⚧️ (foone@digipres.club)'s status on Sunday, 01-Sep-2024 16:10:22 JST Foone🏳️⚧️ it's also a typed VM, so that makes it even more complicated. (Because the types are stored in the executable metadata)

Foone🏳️⚧️ (foone@digipres.club)'s status on Sunday, 01-Sep-2024 16:10:24 JST Foone🏳️⚧️ especially because it's doing this kind of... in-place relocation thing?

Foone🏳️⚧️ (foone@digipres.club)'s status on Sunday, 01-Sep-2024 16:10:24 JST Foone🏳️⚧️ like the bytecode will be:
pvm_Call 0, 0
and then the relocations will kick in and that'll turn into:
pvm_Call Vanna.revealTile

Foone🏳️⚧️ (foone@digipres.club)'s status on Sunday, 01-Sep-2024 16:10:25 JST Foone🏳️⚧️ I'm trying to decode a scripting language for a video game, but the problem it's not just a bytecode file, it's more like an EXE file. It's got multiple sorts of metadata that has to be properly parsed, and linking that needs to be done, and that task is proving to be a little too hard for my tiny brain
