Ya couldn’t get Midnight Resistance, Ghost n’ Goblins, Turrican, Bubble Bobble, IK+, Pirates, Batman, Altered Beast, Nightbreed, Thunderblade and all the Dizzy games for that console thingy on cartridge. Could ya?
You can, but you have to mod it to load new software. You can wire it up to a 1541, if you have one or a 1541 emulator and play games from there too. I think there is an SD Drive for the C64 available now, so that would probably work too. There are quite a few pages online with instructions.
