my advice is to get another emulator, because if it is repetitive, then you might have to get another emulator. I know that I have always had a problem with using ZSNES for SNES emulation, so I had to switch to SNES9x.
dont know your NES emulators, I recommend a FCE ultra if you want higher quality picture, and NNNesterJ if you want an emulator that has really good compatibility with games you save on a regular basis.
