MAME Emulators for Steamdeck

MAME (originally an acronym of Multiple Arcade Machine Emulator) is a free and open-source emulator designed to recreate the hardware of arcade game systems in software on modern personal computers and other platforms. The first public MAME release was by Nicola Salmoria on February 5, 1997. The emulator now supports over 7,000 unique games and 10,000 actual ROM image sets, though not all of the supported games are playable. MESS, an emulator for many video game consoles and computer systems, based on the MAME core, was integrated upstream into MAME in 2015.
