Me and my little brother were playing Teenage Mutant Ninja Turtles 4 Turtles in Time and the day before, we played the game and had no problems but when we played today it was acting strange. While in the middle of fighting our turtles would begin to walk different directions, jump, and would pause the game even when we didn't press anything it would just do it by itself. The console is a new Retroduo (not an Snes) but plays Snes, Nes, and Sega Genesis games. We don't know if its the controllers or the system. Also i cleaned the cartridge with Brasso metal polisher.
