Here is an example of a few of my games. NEC tried their best to maketheir system as advanced as they could. Notice that these are cards. Even thoughthese games may be small, they can pack just as much memory as the cartridges inthe other cartridge based systems! One of the larger games, Street Fighter II ChampionshipEdition, stacks up to 20 megabits on one single card!
Here is a closeup of one of my TurboChip games. Notice the contacts;they plated with real gold for maximum contact and transfer speeds! All of the othervideo game systems use extremely low-priced copper which corrodes over time.
