MAME (Multiple Arcade Machine Emulator)

Client-side in-browser arcade execution is powered by WebAssembly compilations of the mame2003 and mame2003_plus Libretro cores, derived from the historical MAME 0.78 codebase (2003).

MAME 2003 is subject to the original non-commercial MAME license. All credit and gratitude go to Nicola Salmoria and the hundreds of dedicated MAME contributors who have documented arcade hardware over decades.
