I didn't try programming the Mega65 with CC65 yet. I took first steps with CC65 and the Commander X16 though. My code for the X16 would be Please login to see this link. (runs in an emulator). I didn't get very far though. Graphics programming seems to be very system-specific, so probably my code couldn't be ported to the Mega65 easily. Maybe the general principles and the data could be transferred though.
