OKI is a shorthand referring to the kind of Sample chip used by the CPS1, the OKI6295. Wanted to make stuff for the system, so been smashing my head into this topic for a while! To that end, wrote some Python scripts to help ya extract samples from CPS1 games, or to compile your own .wav samples into usable OKI ROMs!
