Master edit: I figured out how to edit/rename/delete stuff from Nesbox library. You have to access the appdata folder from the Xbox Device Portal on PC. As far as I can tell, it cant be accessed from the Xbox directly. I managed to delete the stock roms, and replace my thumbnails with proper cover arts and it looks and feels so much better lol Genesis games are finicky. Regions are weird. Had plenty of Genesis, PAL and NTSC, roms not run.. only for a Worldwide release or alternate rom work just fine. So if you have one not start, try a different region/rom. Also any GBA game that has issues with this emu (Buus Fury in my case, says cant play on this hardware) will work 100% with VBA10.
