Rayman, BIOS Music Player, GameShark Music Players
- cdriso.c: Forward + Backward (rewind) support, Data track wiping during audio play, GetStatus (time) fixes
- cdrom.c: CdlForward, CdlBackward, CdlID (auto boot Music CDs with BIOS), CdlStop, CdlPause, CdlPlay (support BIOS play + pause / resume), CdlGetlocP (timing, output results), REPPLAY (report play times - Rayman, BIOS) now work
- cdrom.h: Forward, Backward states; Larger result buffer
NOTE:
Must use iso images with subchannel data for Rayman and Music Players to work. And use latest PCSX-r PEOPS DSound plugin.
