hmm, since people are talking here again, i had this brilliant idea to put all the roms together on one disc and mr.x's two xbe's. using the cdx menu, i figured i could throw everything together and have both xbe's use the same roms folder. great.....except:
once i threw everything on the disc, everything showed up fine, it's just that metal slug 5 won't load past its p1n rom (freezes), kof 2002 is all glitched up, svc chaos (either one) won't load past.....er, some file i can't remember, but it's not the first one. i'm pretty sure the others are fine, but if ms5 won't work, it defeats the whole purpose of all that work.
and it's not the roms, btw. i tested all of them on my HDD before making a dvd-r, and they all worked using the cdx method. it seems to me that ms5 and svc freeze up right before it goes to the neogeo.zip file. my plan is to put the files from the neogeo.zip into each of the games that freeze up, but that wouldn't solve the problem with kof 2002.
anyway, just reporting in.
