QMC2 v0.243 is released. 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).
