Is there a way to change the configuration to use with x-arcade? Please help. Thanks
Did you try to customize the controls using the x-arcade?
For Arcade/MAME, you need to unlock first the configuration in main menu -> settings (in green section of main menu at the bottom). Then you can change it using emulator menu globally or per game.
For the other systems like the ones powered by RetroArch, for example, you can directly changing it using the emulator menu too.
For arcade pc based systems like Taito Type X, for example, the roms usually have there a file for you to configure the controls.
