It currently supports MAME & GBA emulators and the ports for Wolfenstein and the Doom series. In principle it can support all of the emulators and game ports that RetroPie supports. I'd just need to configure it in RGL (Retro Game Launcher), download roms & artwork, configure the control etc.
As for the name, well, it's named after me. I also build an identical one (apart from the name) for my nephews Thomas and Jasper, called: TJ-Station :-)
