your best options just now are either using mameox0.72 for the midway games or look around the net for the mortal kombat download thats floating about.it has mortal kombat1,2 and3 ripped from the original midway arcade treasures and they are the actual arcade roms and plays flawlessly. neat ill give that a try thanks, my actual mortal kombat arcade board is missing a little speaker looking thing that hangs off it which is why it has no sound bp i have just started testing the beta and its fukin awsome.the autofire is a good idea with using the thumbsticks.been trying out a lot of vert shooters like esprade,raiden,dodonpachi.....and with the screen rotation ecerything looks sweet. im surprised that you thought primal rage always played slow in mamedox coz when you play it with the sound off it plays at full speed,it actually plays faster than mameox128 with the sound off.i fired up neogenesis and compared the speed with the 32x version and there isnt any difference in terms of speed that i could see. as for hyper streetfighter anniversary i know the driver isnt in but i wouldnt bother trying to get it in as the cps2 code seems to get a major kick up the ass when you are trying to update so i wouldnt be to concerned about it just now.
