Well ive spent many hours collecting all those classic beat em up arcade games and i have played and played and felt like I was back in huge arcades in the mall which was great. The only problem is that there are a hand full that I can't get to work no matter what I do. They say that parts are missing in the rom when i audit them and i am at a loss at what to do. More specifically games like oriental legends knights of valour except for two versions of part one, crystal of kings, final fight revenge, age of heroes and many more. I have the pgm.zip and neogeo.zip files where they are supposed to be and i have tried the latest emulator of final burn, nebula, mame32, and mame 144b to try and get these to work to no avail. If u have gotten any of those games to work on an emulator on pc I could really use some help on what I'm doing wrong.
