wai doesn't appear to wait for an interrupt #77

Closed Yazwh0 closed 1 year ago

Yazwh0 commented 1 year ago

wai doesn't appear to wait for an interrupt. If I enable only the vsync the attached .prg should draw one dot every frame, so slowly draw a line from 0,0. (The colour is the value of ISR.) So should be $01 (vsync) + $08 (aflow)

In the emulator as wai is not held, the image is all $08 apart from the one tick where vsync is set. I've included a second .prg where there is no wai, and the output is the same indicating that it is not actually doing anything.

On latest code, I believe Box16 is behaving correctly with regards to WAI. There may have been some fix that went into Box16 that was never ported back to x16emu.

Yeah, sorry, jsut saw that.
