- SYSTEM_INT1: Multiple purpose VBL routine
AES/MVS only BIOS calls
- CARD: 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)
