DANG. SOLVED! When editing Retroarch in associated platforms, I unchecked “Extract ROMs”, unchecked “Autmatically download Retroarch core if missing”, and… here’s where I think I messed up for the past several hours… I had to select the box that said “Force using MAME metadata…” a few pages later. Ugh! Then I selected Import all clones (all selected ROM) and they work!

Hi. Noob here. I do not want a MAME full set. I only want a few old school classics. I downloaded a few of them in non-merged format from MAME 2003-Plus collection. After doing so, I have been able to successfully play each directly in Retroarch using the Arcade (MAME 2003-Plus) core.
However, I am unable to figure out how to configure this Launchbox. I tried “Import Rom Files”, select files or folder, select “Arcade” platform, choose Retroarch as emulator. Didn’t work. I edited Retroarch and selected Associated Platforms and selected “mame2003_plus_libretro”. I tried selecting and deselecting various combinations of Default Emulator and Extract ROMs. After finishing the process, nothing I do seems to work.
Hopefully what I’m doing wrong is very obvious to somebody here. Please help! I’ve done searches and most results are how to import a full set or people saying that the poster likely grabbed a merged file instead. The fact that mine plays directly in Retroarch makes me feel like it’s a correct non-merged MEME Rom.
