Ok so apparently the romset i used was meant for mame32. I downloaded it and it works currently im scanning some snes roms and after that i will see if it works over launchbox. Thank you so much for the help.

Didnt worked

So i just tried launching mame outside of Launchbox again and now it says "The selected machine is missing one or more required ROM or CHD images"

Ok i managed to fix the Gba Problem, i had a typo ?‍♂️

Im using the 64bit command line version of mame. Under the associate tab i have Arcade for mame and for the gba i have Nintendo Gameboy Advanced as core mgba_libretro and its checked as default emulator.

Hey, im new to Launchbox and this forum and i think after going through a ton of frontends i finally found the best one Sadly i have some problems getting Gba and Mame to work. When i try to start a Gba game it just loads for a second but nothing happens. As Emulator i use Retroarch with the mgba_libretro core. I have selected the right core in the emulator settings and over retroarch it runs without a problem. When i try to start Mame games it shows up for a second says initialzing and then closes down (im using Mame itself not the retroarch core) i have already searched for hours but just can not find the issue.
