I now have a way to backup/restore game saves for most SNES games with my SF7. It is a good feeling to take an old game I could never finish, and complete it with the help of save states, etc. even if it is technically cheating.

Now I am looking to do the same thing with other cartridge based systems, mainly NES, Genesis, and N64 games that do not support the memory card. Are there devices that allow this? I have no real interest in backing up the ROM of a game or playing backed up ROMS on the system. I just want to preserve the effort of all the wasted time of my childhood.

Thanks.
