The current SVN revision (r240+) includes a new feature to import/export global and game-specific MAME configuration files (mame.ini/gamename.ini in case of SDLMAME, or xmamerc/gamenamerc in case of XMAME). This enables you to easily exchange MAME configurations between different QMC2 installations, and to run MAME with the exact same setup regardless if it is launched via QMC2 or from the command line (or how ever).

Also note that the preview packages have been updated to include images for over 6400 games. See download section!
