Uplink PC to Genesis to use ROMS on console...

Hi, I have had a question on my mind for a while:

I have the original sega genesis (as do many others) and I was wondering if it is possible to create a "link cable" from say either a serial, parallel, or USB port which would essentially "dump" the ROM file and it's contents to the input of the console.

To sum it up: use a ROM on the original console (I understand this might not have much to do with Emulation, but I didn't know if this was possible or not?)

Maybe this could be done on a smaller scale first? I was thinking maybe a NES? Since a NES is 8bit and a serial port is 8bit...I am not very familiar on any of this so if my logic seems out of wack...let me know.

No matter what, please reply to this email A.S.A.P. to let me know what you
You'd need to have memory somewhere to emulate it, at which point it makes more sense to just use a copier or Flash/DRAM/SRAM/EPROM cart. Using the PC's main memory won't work because you won't be able to get it to the Genesis fast enough over any standard expansion bus...
