This RETRON 5 plays Super Famicom games naturally. But none of these cartridges fit. Actually, these are FamiCom games not Super Famicom games. Which work with an available adaptor for Nintendo and Super Nintendo.
[Cont] There are ports for controllers for all the Nintendo and Sega standard controllers. Which doesn’t make sense. Why would someone that owned all these systems and cartridges also need this thing. The thing on the back is for even more Sega stuff. Sega games aren’t bad but almost never have any Save option.
