Ok, here's the deal. I can't seem to get my game genie to work with my NES Yobo remake system. I can get the game genie to turn on with the code screen but I can't get that screen to come up when I have a cartridge inserted in it. And I tried this with two different game genie's. The games I tested work by themselves and so do the game genie's(I tested 2) but when ever I try to run them together they don't register. So my question is: will a game genie work with a Yobo Nes or do I need to get an old school Nes system to run it properly? And if I do need an old school Nes, are there any other alternativs to use with my Yobo system?
