- SYSTEM_INT1: Multiple purpose VBL routine
- CARD: Perform memory card operation
MVS only BIOS calls
- READ_CALENDAR: Read the current calendar values and update the relevant BIOS RAM locations
- SETUP_CALENDAR: Set the calendar values to the data from the relevant BIOS RAM locations
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)
