Would be slow. Why not just use an eprom, either parallel interface, or serial, and use it directly?Can get really big eproms these days.Or use arduino to load up sram from SD card, then let sram be accessed directly.
Also, using an EPROM, I want to be able to load, wipe and reload easily.
Is there a primer or similar project I could use to build the theory?
OK, just thinking about the dual porting issue, if you are happy to only program while the cart is NOT plugged in you don't have a problem, pull it out to program, plug it in to play.
How would I program the EEPROM though?
