Lol again that was stupid of me. I completely understand your diagram. My mind was just over complicating things. This is definatly way better then what I was thinking. I don't suppoese there is anyway to make a NOT gate out of OR gates is there? I seriously doubt it. I did see that the cmos chip co...

Thanks for the replys guys! I doubt I could figure out how to get a 4066 to controll disabling the carts, I'm not that experienced. But just setting a few pins high is dooable in my eyes! Ill just have to fire up a schematic on how to get it bumping with the DPDT switch I already have wired with my ...

I trying to hardwire in a game to my NES (TMNT 2 mmc3b because it had a crack in the case, so its a tester) and be able to ...
