Some NES (Famicom) games has weird graphical glitches / some .pce games won't load

So I tried some NES (famicom) games and they have graphical glitches and some .pce only loads into black screen but it isn't for all the roms and I can't figure out why. It doesn't appear to be the rom file because they load fine on a Software emulator. Any possible things I can try?
