I never knew you could load a cheat rom to use cheats then load a game rom, would this work better than using SC63s cheat system.Summercart64 allows chain-loading a N64 cart and a 64DD disk together, not sure if it's supported with "cart+cart" but have you tried chain-loading the N64 Gameshark ROM and the game you want to play?
I've tried this way but with it been beta it has issues, I've tried using rom injector but I can't seem to get irs GUI to open, maybe because I'm using W11.
