You have UI_CANCEL included, but it's mapped to mame's default so it doesn't need to be there. Nice work, and thanks for contributing! (I'm always happy to see others also using the ctrlr file.)

To use, download the TXT attachment below and save it in your MAME CTRLR directory as XArcade+XBOX360x4.cfgįinally, edit your mame.ini file, located in the INI folder within your MAME directory, and change the CORE INPUT OPTIONS values to: Player 1 on either X-Arcade or XBOX 360 pad are able to navigate through MAME's ingame menus. I did this to prevent accidental exits, etc. Disabled the X-Arcade shortcuts KEYCODE_2+KEYCODE_4 to exit the game, as well as KEYCODE_1+KEYCODE_3 to bring up Options. Support for dual joystick games using the XBOX 360 left and right analog sticks for games such as Smash TV, Robotron, etc. Enable mouse and light-gun support within mame.ini should these devices be used. These devices are configured for the X-Arcade joysticks, XBOX 360 controller left thumbstick and digital pad, mice/trackballs, and light-guns (when applicable). Support for analog devices, such as paddles, dials, flight yokes, steering wheels, and light-guns. The configs match the default gamepad layout for Street FIghter IV PC and XBOX 360. Modified Street Fighter 1, CPS1, CPS2, CPS3, and Killer Instinct series controls for the XBOX 360 pads. Corrected configs for Mortal Kombat 1-4. XBOX360 pads are configured to use the same control layout as the Neo Geo CD gamepads. Specified controls for Neo Geo games, which use the MVS style button layout on the X-Arcade. Both analog and digital pads are mapped to control movement, as well as analog triggers for some games. Here are the details for this configuration. I created a customized MAME ctrlr file for use with the X-Arcade, as well as 4 XBOX 360 gamepads (wired or wireless). Anyway, I figured someone may find this useful.
