Hey Thanks for your reply Most of my roms on retropie/retroarch on mame2003/2003+ core, i know that much. For some reason they still wont load if I select that core. I am not sure if I am doing something wrong.

Hey Guys I am new to launchbox and still finding my feet and need some assistance. I have set up several emulators such as snes, sega etc, but I am having trouble opening mame roms. I have over 4000 roms in one folder and I dont know what mame set they are part of. I need the correct steps to import these roms into LB such as mame version to use etc. Can someone please assist? Thanks in advance Chris
