Registers

  • What are $380011, $380061, $380065, $380067, and $3800E1 used for ?
    • smkdan: I noticed one time I tried running a burned BIOS that didn't have those init regs on my MV-2F and it was permanently stuck in a reset loop. AES BIOS doesn't not have that code and is known to not work on real MVS. It's probably MVS specific init code for neo-b1 or protection to stop bootleg BIOS running on MVS? will confirm later on.

SP-E init code:

	move.b	d0,$380065
	move.b	d0,$380067
  • CD registers
