A collection of Python scripts to extract samples/compile .wavs to ROMs

Python Scripts designed to Extract/compile Samples to and from CPS1 games. Simply add the unzipped game to roms, generate resources if ya haven't already and have fun! Scripts made with Python 3.10.6

• GENERATE RESOURCES The script reads capcom-cps1.cpp and isolates every game, outputting a resource file for every compatible game containing the names of every OKI ROM as well as their sizes

• OKI_EXTRACTOR The first 0x400 bytes of OKI data are reserved for pointers to each sample, the first 8 bytes always being 0x00. Pointers are laid out like this xxxyyy00 xxx - Start Point of Sample data (24-bit) yyy - Start Point of Sample data (24-bit) This data is included in the names of each sample. Resource files are required to read the names of each OKI ROM in roms/(game)

• GENERATE_OKI_ROM Takes every Sample in COMPILED_OKI/input_wav/(game), compresses them to 4-bit VOX ADPCM, and generates OKI ROMs with it. These files can simply be inserted into a given CPS1 game, and the script outputs these compressed version individually in COMPILED_OKI/compressed_wav/(game). Resource files are required for when compiling ROMs in the case there are none in roms
