QMC2 is a Qt 4 based multi-platform GUI front end for several MAME and MESS variants. The included binaries are known to work on Windows 7, Windows Vista and Windows XP using the original MAME and MESS variants (MAMEUIFX32 is supported as well through a replacement template for the MAME variant).
Features:
- Extremely fast drawing of game/machine images, optionally smoothly scaled (PNG images, buffered in a resizable LRU-cache)
- Support for game/machine icons — historically only PNG images, but when stored in ZIPs, nowadays also ICO format is supported
- Icons and all game/machine images can either be stored as individual files in respective directories or they can be combined and compressed in ZIP archives
- Easily extensible template-based emulator configuration scheme (defined through an external XML file)
