Features

iNes was the 2nd Nintendo Emulator System ever released (1996!) after Pasofami, but was the first to be truly easily usable. It also supports the GameGenie, Family BASIC Keyboard, FDS and the VS-System arcade system. iNES offers several graphic filters and even supports online gaming. It has since been ported to Unix, MacOS, MSDos, Windows, Symbian, PocketPC, etc.

Most Recent Changes

• Added optional frame rate display and should support most command line options on Windows. I have also improved sound reliability on Windows. The previous iNES release has added support for homebrewn UNROM-512 (mapper #30) and Cheapocabra (mapper #111) cartridges. This allows running recently written NES games. If you have an Android device, the iNES-Android has now become part of VGBAnext, my universal GBA, GBC, GB, and NES emulator, with the free APK available from this site. I had to do this because Google Play thugs have banned the original iNES app saying that its built-in NES cheats "violate Google Play policies" (really?).
