======================= Mame keyboard shortcuts ======================= First published at 8/4/2021 on https://defkey.com/mame-emulator-shortcuts Mame is a free and open-source emulator aiming to recreate the hardware of arcade game systems in modern personal computers. MAME was first publicly released by Nicola Salmoria on February 5, 1997. It now supports more than 7,000 unique games and 10,000 actual ROM image sets. Mame has 165 shortcuts and we have listed all of them below.
