Generic BIOS calls
BIOS calls common to every system.
- BIOSF_CLEARFIX: Clear fix layer
- BIOSF_CLEARSPR: Clear sprites
- BIOSF_VBL: Multiple purpose VBL routine
AES/MVS only BIOS calls
- BIOSF_CRDACCESS: Perform memory card operation
CD only BIOS calls
- BIOSF_VIDEOEN: Enable/disable video layers
- BIOSF_UPLOAD: Upload data to DRAM
- BIOSF_LOADFILE: Load file from CD (with animation)
- BIOSF_CDPLAYER ($C0055E): Reset to CD player
- BIOSF_LOADFILEX (?) ($C00564): Load file from CD (no animation)
- BIOSF_CDDACMD: Issue CDDA command
CDZ only BIOS calls
