It may also be more accurate than the other nes emulators I tried. There was this odd sprite glitch in castlevania that I couldn't get rid of before but I haven't encountered it on this emulator. very happy with that.

This emulator was a godsend for me because none of the other emulators I could find were as accessible for me. By which I mean I settled on GPFCE up until now because it was the only one with a simple pop up menu and some options, but this is so much better. Easy and customizable.
