Jnes is a closed-source Nintendo Entertainment System emulator for Windows and Android.


Jnes is not very accurate, with other NES emulators being more compatible as well. There is no good reason to use this emulator over more accurate ones, unless performance is an issue (which it shouldn't be, for an NES emulator). For Android, since this is payware, there are certainly other, better alternatives, such as RetroArch (using the Nestopia/FCEUmm cores).
