GMAMEUI is a front-end for MAME on Linux. It helps the user play and configure arcade games more easily. GMAMEUI is an enhancement of GXMame, fixing a number of long-standing bugs, including adding support for SDLMame in preference over the now-obsolete X-MAME. New UI features were also added.
LinuxConsole is a live and modular Linux distribution that can be started from CD/DVD, hard disk, floppy disk, USB disk, or network card (PXE). The use of "console" in the title doesn't mean that it is started in "console" mode, but is meant to symbolize the simplicity of using it. This distribution is as simple to use as a game console: you can start applications without installing them. It is modular: there is a common base (device detection, GUI) and optional modules for multimedia, communication, and servers. The goal is having a very fast startup (less than 20 seconds), very good hardware detection, and many applications available (not just games).
