If you plan to run a NES (Famicom, Dendy) game on your computer, you will need a NES emulator. First, you will need to run an emulator and after that you can run a game in that emulator. Emulation, an imitation process of some system – is a very resources-consuming task and may require the performance from your computer, a lot above the performance of the emulated system itself. The more complicated the emulated system and the emulation accuracy are – the more performance is required to run it. Emulation accuracy is the thing that emulated programs (games) compatibility depends on. For instance, if an emulator does not consider some, even smallest, detail of system feature, used in some games, these games will not run, or will work incorrectly, while other games may wor
