In SX Microcontrollers, SX/B Compiler and SX-Key Tool, bean wrote: 1) Not possible. As you say the SX cannot run code from an external device. 2) Would be nice because the user could make their own games and/or modify the games (cheat). 3) Would be the most practical for a small number of games. You could simply connect the MCLR pin of the "game" SX chips to output pins of the "menu" sx chip. Only if MCLR is high will that SX run. BTW: I'm working on making the driver work with PAL also (require recompile though). Also the timing has been tweaked because some LCD video screen would not work. I will post it later this week.
