Changes

Currently, over 660 systems are supported, including the CPC and CPC Plus ranges and the GX4000. This is probably the main reason for using MESS, that a single download is enough to emulate more or less every home computer and gaming console that ever existed in the late 1970s and 1980s—provided one can find a ROM set that works (see below). MESS does not have the depth of other emulators, but it sure has enormous breadth. Its flexible input mapping and MAME-compatible pixel shader effects make MESS particularly suited for gaming.
