Kirby's Dream Land 3:Audio

This is a documentation of Kirby's Dream Land 3's Audio Files.

Sound Driver

PC: 0x103EFC
SNES: $D03EFC
ARAM: $0700
Length: 0x9FC bytes.
Uses the standard N-SPC as a base, however, the game only uses tempo values 2E, 2F and 30 because tempo affects sound effects too, therefore, the songs use non-standard note lenghts to simulate tempo. The panning table is inverted, normally 00 - 14 would be Right - Left, but in this driver it's the opposite (which makes more sense to me). Percussion Set command does nothing as it's in a fixed value of 23, this may be because each sound effect sets the command to 23. The driver is not programmed to deal with SFX interrupts correctly, so every stage song must use 5 channels or less.

Sample Pack Usage

PC: 0x10CA2E
SNES: $D0CA2E
Length: 0x2B bytes.
Each byte corresponds to which sample pack each song will use, the order of the bytes is the exact same as Song IDs. You must input the ID of which sample pack you want to use.

Sound Effects?

Sound Effects start at $3400 in ARAM and at $CEA1F3 (PC 0x0EA1F3) in ROM, I can't grasp how they exactly work though, they behave like normal sequence data but I had trouble understanding how their pointers work.
