Oh did I mention the funny screensaver – a slide show of error messages of numerous systems? The interface does not rely on X-Windows and is written in Python. We will use CHAMELEON PI, as it so nicely combines most common emulators in one single Raspbian based IMG file for the Raspberry Pi. Not only does CHAMELEON PI combine a nice set of emulators, but it also offers a nice menu interface to select your emulator of choice. Note: ChameleonPi no longer seems to be actively developed, but can still be downloaded.
Just to name a few very good ones: MAME4All, RetroPie and of course Shea Silverman’s efforts. Let me first say that there are some great alternatives to CHAMELEON PI.
