Hi, how about intercept the jump to the ROM coldstart vector (e477), like we're intercepting SIO. And maybe also a virtual CIO device to control the Emulator. The latter would be the best option I think. Regards, Peter. Gesendet: Samstag, 26. Juni 2021 um 17:34 Uhr Von: ata...@li... An: ata...@li...

Do you have ideas how the "Atari program" <--> > "atari800 emulator" communication should look like? 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.
