I have been spending the last 4 rainy days trying to get Retroarch with Libreto Mame working without any Luck. I have tried installing 0.39B ROM - 2010 Roms and FBA roms all without any luck I have loaded the CORE once losed they cant be removed so I reset the box and reinstall everything again.
The controller works within the main menu but for some unknown reason does not work 100% all the time in consoles or after launching a rom. I have exhausted all the avenues I have but I can shed some light to help diagnose the problem. MAME4DROID works with a large number of 0.39B roms. SNES9X works with but controller delay is just crazy. they work outside of retroarch but not in the cores provided… I have run all database and asset updates and even the profile updates but still no luck
