QMC2 v0.42 is compiled. QMC2 is a good GUI for MAME & MESS. QMC2(M.A.M.E. Catalog / Launcher II) is the successor of one of the first XMAME/MESS GUI frontends available, QMamecat (derived from MAMECAT, which was text-only). QMC2 has been rebuilt from scratch as a Qt 4 project. Parts of the design and code were inspired by its predecessor. The new design was made as flexible as possible to minimize dependencies from frontend- and CLI-related MAME changes, which was a major deficiency of QMamecat. QMC2 uses a template-based MAME configuration scheme, which can easily be enhanced with additional command line options (defined in an XML template file).

QMC2 v0.42 Changelog:
fix: changes to global emulator options weren’t correctly merged with the current game/machine-specific ones when the corresponding save-button was pressed and ‘overwrite’ was selected on the subsequent dialog
fix: don’t add ‘ghost sets’ to internal master list when creating category- or version-views
fix: don’t allow initial ROMAlyzer setup while reload is active
fix: do final update of the progress bar before sorting the game/machine list after a reload
fix: emulator configuration widgets now honor the current style’s highlight coloring for check-box (bool) type delegates
fix: corrected sRGB profile headers of all included PNGs
fix: software-list: favorite software wasn’t shown initially when software-state filtering was active
fix: ROM check: the ROM status indication for the currently selected game/machine wasn’t always correctly updated on-the-fly for ‘not found’ sets and sets w/o ROMs
fix: software-list: corrected combined state- and compatibility-filtering
fix: MESS device configurator: don’t show slots that have no user-selectable options
