i had another idea, ive spoken to my engineer friend and he suggested having a BIG flash rom in the cart soldered in (unrom cart for example) with a microchannel socket situated on the cart somewhere which directly links to the flash which can be directly linked to pc to flash and reprogram with what ever you like if not more than one program and a trigger to switch between games and i had another idea, in that do you think it would be possible to make a super gameboy equivalent for the nes except that its full screen and plays through the nes- sort of like the hellraiser cart except the processor on board could be a z80 with direct link to a compatible socket on the cart to play gameboy games... its an idea and my engineer friend has worked with 6502's and z80's quite alot so he (being the brains) might make something out of it, im gunna give him my old frontloader nes and my snes and n64, cause he is intrigued by them, i might nudge him into making a copy-n64 (maybe), i also thought of that myself.... make a ram/flash cart and plug a cable into the expansion port in the bottom that can download roms from the net onto it or something like that anyway, its only fantasy, but wouldnt it be grouse!!!!
