Registers
- What are $380011, $380061, $380065, $380067, and $3800E1 used for ?

move.b d0,$380065 move.b d0,$380067
- CD registers
Others
- CMC fix bankswitching: how/when is vram bank info sent to the cartridge?
- neo-mga on mv1a + PALs, neo-sdr and neo-dcr info
- CDDA playback (needs more research in cd bios)
- neo cd chip pinouts (not very useful)
- dump lc98000 version neocd bios
- pro-b0 and pro-c0 pinouts
