Is the CD player and all it's grapics (CD+G stuff) on that 3.1 ROM chip for the CD32?
IIRC in the CDTV all that type of stuff was on a different rom and it just had the standard 1.3 rom in it.
I have an old CD32 that died and it has the single 1meg rom (I believe some CD32s had the 2 rom setup like the A1200). It would cool to make a rom switcher that could use that 3.1 ROM in my A1200.
