JoeB,
I would like to use Nebula with MAMEwah, but I am running into the problem with roms as Nebula only recognizes 50-60% of my Neo Geo MAME roms while MAME recognized all of them. What are you supposed to do when Nebula doesnt recognize the roms? Are there Nebula specific roms? Shouldn't the roms that worked with MAME, also work with Nebula?
