alright, i have a 4 slot mvs cab slot 1 has metal slug, slot 2 has rage of the dragons, slot 3 has ninja combat, and slot 4 has art of fighting 2 installed right now. all games were working fine the last time the cab was used. this time, when i turned it on, every game except rage of the dragons worked fine. nothing was changed since the last time it was working, but for some reason, when i go to play rotd, i get a black screen with red words warning me about offical roms. i bought this game brand new from the neo store and had no problems with it until today. anyone know what the problem could be. i could get the exact error message if needed.
