| PSX Address | Declaration | Description |
|---|---|---|
| 0x80029818 | void AkaoLoadInstrSet(const void *sampleSet, const void *instrSet) | Load additional instrument set
sampleSet: corresponding to SOUND/INSTR2.ALL instrSet: corresponding to SOUND/INSTR2.DAT |
| 0x8002988C | void AkaoInit(const void *sampleSet, const void *instrSet) | Initialize sound driver and load initial instruments
sampleSet: corresponding to SOUND/INSTR.ALL instrSet: corresponding to SOUND/INSTR.DAT |
| 0x8002DA7C | int AkaoLoadSeq(void) | Load and start playing new AKAO sequence
Parameters are given from a global structure Returns: 0 for success, 1 for already loaded, and -1 for invalid signature |
