Actually implementing ISP (x)or MSP would be not too hard, but implementing both and do the switching at correct times seems more cumbersome.

I found it: Quik the Thunder Rabbit (for example "Quik the Thunder Rabbit (1994)(Titus)(Disk 1 of 3)[cr PDY].zip"). M-bit and MSP is set before "Loading" screen appears and stays set in Start Game/Password/Normal screen.
EDIT: I recommend first implementing only "storage" for those registers so that MOVEC to <currently unimplemented 68020 register> filters unused bits and MOVEC from same register returns stored value. Then run tester MOVEC test again.
