Enable cheats on LB Arcade MAME!

[RetroExecutioner]

Does anyone know how to open the service menu in MAME on LB using an Xbox controller?

I want to add a specific button on the controller that opens the menu. How do I do that?

It has nothing to do with LaunchBox. It's all via MAME.

If you're referring to the menu that you get to when in-game, you press Tab...

• Open MAME (In LaunchBox, right-click an Arcade game and select Open MAME)
• Go to General Settings - Input Assignments - User Interface
• Set whatever button to the 1st item Show/Hide Menu
• When done, press Escape - Escape (and then I think you need to...) select Save Settings

Good to know, but I see it's only possible on the keyboard. I want to assign the menu key to a specific button on the controller, but pressing that button does nothing. Is there a way to select a button on the controller instead of the keyboard?

I tested it before posting (that's how I knew the steps to write ) and it worked then.  Make sure your controller is on before starting MAME.  With Show/Hide Menu highlighted, press Enter then press "the button".

Note: The Guide button won't work for this.  MAME doesn't "see" it.

I tried, but it doesn't let me choose the guide button; all other buttons work, so I have to select any other button, unfortunately

You never mentioned that was the specific button you wanted to use.  But my Note (above) did cover that.

Or get creative (now that I know that's the specific button you want to use).

• (In LaunchBox) Edit your MAME emulator
• In the Running Script section, add

  • SetKeyDelay, 125, 50
    $vk07::Send {Tab}

• If there's something in there already, add it to the bottom
• Click OK to save & close
• Play games and cheat to your hearts content

At the end, I chose a different one; it seems to be working well, but I will also try your way. Thank You!

I would like to know if there is a similar menu system like MAME's on other platforms, such as NES, SNES, Xbox, and Xbox 360. PS123, etc

That all depends on the emulators used for each platform.  And if they do have an accessible in-game menu system, you might/should be able to remap the key(s) similar to what you did with MAME.
