Thanks for the info, Six. Any ideas about the methods? I know they can use a flash card or a cartridge, but I don't have a system in hand yet to look at the addressing.

I'd like to look into the bootleg carts + games first.

I think it's important that this system be emulated. For one thing, most of the titles are new classics. For another, some versions have been declining rapidly by way of 'upgrades' which overwrite original factory data. Finally, "Turbo Outrun" -- need I say more? If people with access to the hardware don't make an attempt it will never happen.
