There is already a feature request for this (Issue #5109). Everybody with acces to the Launchbox bitbucket may vote for this.

@Gadget: If you are importing ROMs for MAMEUI64, you might have the same problem which I already reported as an error. The "Ready to Import" panel is always empty. Other MAME implementations seem to work. It seems that Launchbox is calling the MAME emulator to gather some additional information, and the call to MAMEUI64 fails. I hope this will be fixed by Launchbox (or MAMEUI64), because this is currently my favorite MAME implementation.

Thanks a lot! I did it in a similar fashion. However, I didn't use a bat file (instead: give Launchbox just a fake file which does nothing). Then I setup Retrorarch with the correct commandline parameters in Launchbox. E.g. for Cannonball (prepare for some German screenshot incoming!): Note the command line parameters: the third argument must point to the epr-10187.88 from the MAME outrun.zip. (As you can see, I have Launchbox installed on E:\Launchbox - adapt to your installation as necessary). My problem with the bat files was, that there always was a window opening of the command shell. The solution with using Retroarch from Launchbox directly works like a charm. From the other two games I tried, Mr Boom is the easiest to setup. Just download the core in Retroarch and provide the following command line: -L "cores\mrboom_libretro.dll" Btw great game (up to 8 players) and Retroarch takes care of the gamepad mappings! Cave Story (NXEngine) needs a little bit more of preparation. See https://docs.libretro.com/library/nxengine/ on how to download the content. Then use the following command line: -L "cores\nxengine_libretro.dll" "E:\LaunchBox\Emulators\RetroArch\downloads\Cave Story (en)\Doukutsu.exe"

Hello, as the title says: How can you add the games built-in as cores in Retrorach (e.g. Minecraft, Quake, Cave Story, Mr. Boom...) to Launchbox?
