Two obvious choices: either a virtual HW register or an illegal/unused
CPU opcode. The virtual register approach is more error prone, I feel,
so I'd go for a special CPU opcode. I think it would be smart to
implement something compatible with another emulator as I guess other
Atari800 emulators implemented similar thing already.
