I know a way to detect Z26. I stumbled upon it while working with the AtariVox. (The high score tiable in MGD should not show without an AtariVox connected - works fine on the real hardware and in Stella, but it still displays in Z26.) lda #$00 sta SWCHA ldx #$ff stx SWACNT sta SWACNT lda SWCHA beq z26_detected That's not exactly what I have in my code, but if I understand correctly why it happens that should do the trick. > So, my question is -- should this 'exploit' be published and > thus allow the emulators to more correctly emulate the > hardware Yes.
