Bordeaux is a Wine GUI configuration manager that runs winelib applications. It also supports installation of third party utilities, installation of applications and games, and the ability to use custom configurations.
pLauncher allows you to centralize all of your emulator/ROM launching needs. It is open ended enough to allow the launching of any emulator (xmame, snes9x, xmess, vgb, dgen, WINE, etc.) and its ROMS/binaries.
