LaunchBox not executing games that are selected

[chuckjayne]

I have MAMEUI32 loaded as my MAME emulator all games work outside LaunchBox with this emulator.

I verified that the games are also in the roms folder in MAMEUI32 emulator

Any help will be appreciated

What version MameUI32 are you using?

Depending on how old/new it is you may need to do a couple things. 
 

1) Make sure the Mame.ini file (not to be confused with the MameUi.ini) is located in the root Mame folder (same spot where the mame exe is)

2) if it is an old version you may need to remove -keyboardprovider dinput from the command line box in you emulator setting in LB.
