Using MAME

When you start MAME4iOS, you are now presented with an updated and native iOS/tvOS MAME UI

MAME UI Controls


Adding ROMs to MAME4iOS


For iOS users, you can download ROMs using Safari and save them to the roms directory by choosing the “Save to Files” (go to “On My iPhone” -> MAME4iOS) option after downloading a ROM.

You can also use the “Start Server” option in the menu to start the webserver, and enter the address shown on the web browser on your computer.

You can also use the “Import ROMs” option to open up the native iOS file browser and load files that are saved locally or that exist on iCloud.

You can use “Import from iCloud” to download ROMs previously uploaded to iCloud.


on tvOS the only options are to copy ROMs via “Start Server” or downloading via “Import from iCloud”.

Adding Softare to MAME4iOS

MAME4iOS supports two types of Software

  1. Software List (aka MESS) based software, installed via ZIP files into roms

  2. Single file based image (cart, flop, dsk, …), installed into software

MAME4iOS includes a set of Machines/Systems that dont need any ROMs installed to run, and can be used “out of the box”.

Dual analog support

The right stick on the extended controller profile is fully supported, with support for 4 players (thank you @DarrenBranford!)

Trigger buttons

The trigger buttons are mapped to analog controls and should be useful in assigning for pedal controls, for example.

Touch Screen Lightgun Support (new in 2018, iOS only)

You can now use the touch screen for lightgun games like Operation Wolf and Lethal Enforcers. Holding down your finger simulates holding down the trigger, which is mapped to the “X” button. Tap with 2 fingers for the secondary fire, or the “B” button.

In full screen landscape mode, you can hide the onscreen controls using the “D-Pad” button at the top of the screen. When using a game controller, the top button of the screen opens the menu to load/save state or access settings.

Touch Lightgun setup is in Settings -> Input -> Touch Lightgun, where you can disable it altogether, or use tapping the bottom of the screen to simulate shooting offscreen (for game that make you reload like Lethal Enforcers).

Shortcuts while in Touch Screen Lightgun mode

Turbo Mode Toggle for Buttons (new in 2018)

Under Settings -> Game Input, there’s a section called “Turbo Mode Toggle”, that lets you turn on turbo firing for individual buttons. Holding down the button causes the button to fire in turbo mode.

Touch Analog Mode (new in 2019, iOS only)

Also in Settings -> Game Input, you’ll find a section called “Touch Analog” and “Touch Directional Input”. “Touch Analog” lets you use your touchscreen as an analog device for games using input controls such as trackballs and knobs. These include games like Arkanoid or Crystal Castles. You can adjust the sensitivity of the analog controls, and also choose to hide the d-pad/analog stick in this mode.

“Touch Directional Input” is rather experimental and is for vertical shooters so you can move around using your finger. It still needs some work so just a word of caution :)
