quick question I have windows ME and i dont like playing KOF 2003 on KAwaks because i cant get most of my moves off (hcb, hcf, maiden masher). I d/led mame but it asks for the Unicows.dll file and gives me an error message. Where do I put the dll file for it to work. I also have the same problem with FBA i have some kind of "vidlnit error" i really dont like XP cause it bogs my comp down. Can anyone help me with this problem??
