This classic game doesn't need much introduction, especially friends who were born in the 80s will definitely like it... When you get tired of playing computer games, you can relax by playing a round of Tetris or Super Mario...... This emulator is a Chinese version and also supports game controllers... Other settings are very simple, you can figure it out yourself.
Controller and Keyboard Settings:
Open the emulator and click: Settings---Input Device---Controller 1
There are keyboard and controller 2 columns inside... You can customize them... Those numbers are just parameters of the emulator... For example, when you press "W" on the keyboard for "up", the number "87" appears... Just keep trying and you'll get the hang of it quickly...
If you're not satisfied with this emulator, you can choose and download various emulators yourself...
B is the start button... K is the A button... J is the B button
