The Saturn BIOS does not (un)initialize the DSP. Without zeroizing the DSP
program, the SCSP DSP appears to have a program that continuously writes to
0x30000 through 0x3ffff in sound RAM, which has the effect of destroying any
samples stored there.
This demonstrates the most basic possible SCSP usage.
Strangely this does not work in Kronos, only in mednafen and on real
hardware. I'd like to find a hack, if possible, that fixes Kronos
playback.
