rather than hack my way into having a disk that'll work when mounted in DOSBox, I'm just going to make it work properly if the files are copied to DOS? I'll stick the information from those sectors into a file, and swap the raw-sector interrupts out for a simple DOS read-file-data routine.

in fact, I might be able to steal one from elsewhere in the EXE

weird. I can't find any DOS file interrupts. I know this is for DOS 2.x, but it's gotta load files somehow... there's a high score file!

oh wait I searched on "int 21h". but there's a generic interrupt mechanism here, I just described it. I'm an idiot

btw, the game (Rogue, if I didn't mention that before) is written in C, and uses Lattice C 2.00.

Ghidra mostly decompiles it properly. The function arguments sometimes confuse it: Lattice seems to add some padding between arguments sometimes? I'm not sure why exactly.

this game is so old it doesn't support directories

@foone@digipres.club The only version I have (and had back then) is cracked so it's interesting to hear how they got there.
