I also had a game genie. There was a tendency for the nes to bug out when the gg was in use, but not when it wasn't. The thing is though, the issues started to manifest more and more over time even when the gg wasn't in use. There certainly felt and appeared to be a correlation between the use of the gg and the console not working properly anymore.

That said, I definitely used said Mario cheats and modifiers, also battletoads, and quite a few other games. Flicking through the old glossy paged code manual was always fun - I even bought a couple of games I had previously rented or borrowed based on the extra help the gg could give.
