Game boy games wont launch (anwsered)

[mattman32100]

im very new to retroarch and launchbox. i was able to move a couple hundred roms for snes, n64, GBC, and GBA games just fine. the snes and n64 emulators launch fine but the gba and gbc do not launch. i can launch it directly through retroarch but i cant figure out why it wont launch from launchbox? any help. (i have mGBA for GBA and TGB Dual for GBC)

Have you told Launchbox to use those cores in tools/manage emulators/retroarch/associated platforms?

Its fine.  Its often a step overlooked by newcomers. Launchbox needs to know which core to tell Retroarch to load with the game, as you can see a lot of these are pre populated in that screen, but if you want to use a different core you need to click in the core cell and use the dropdown to change to the core you want. Also if the platform you want to use isnt listed at all, then scroll to the bottom of that tab and double click in the empty cell to add whatever platform you like.
