What kind of hardware do you use to program the 7800?
Mainly my CC2 and PAL 7800 for initial testing. I'll fire up the game on my NTSC console if I think VBLANK time is going to be tight and to choose colours. All my games auto-detect the TV type and configure themselves correctly for display lines, colours, animation frame display times etc. It means I only have one lot of code to maintain.
