So I was playing around with my new EverDrive, and I noticed I kept getting glitchy jumps TMNT II. I figured it was a problem with the cart, but I got out my legit copies, and they did the same thing. I've also dumped said carts myself, and tested them in the more accurate NES emulators (Nestopia, Nintendulator, puNES) and couldn't reproduce the effect.
I pull out my two spare systems, and the same thing happens on them. I swapped to a different power supply, and no change. As a last check, I happened to swap out my controller, and lo and behold, the effect is gone! Does anyone have any idea what might be going on that could cause such behavior? I don't plan on using that controller for anything other than parts from here on out, but it's very curious. I uploaded a video, just so folks can see what was going on.
