you make an excellent point sir, i have been downloading and compiling a list through all kinds of places. Starting over with the fbl roms, just redownloaded the 1.19,and 1.20 updated roms (full 1.18 set downloading now, much bigger), and even just the 20 or so the updates have, I can play everything, except the mslug2 that was in there. something about the neo geo games. Is it possible my xbox is an older model with less ram? don't know if they have multiple versions, but seems like anything past 1995ish has trouble
