I'm releasing this as a public beta version, which means it is a work in progress. This has very limited testing and I am sure there is a lot of issues that need to be fixed up. This is an actively developed emulator so more to come.
No games are included with this download. Dump your own real N64 games, or simply play free homebrew games, which are available online. Put those games on your SD card / USB storage to be able to play.
