If you don't know what mugen is let me school you up on some thing.... Mugen is your own 2d fighting game engine its like your own marvel vs. capcom except with you choose everything from graphics to chracters. You can make your own chracters and stages.Its the S***!
There is a new mugen called 2000.627 version you can get it at elecbyte. But I recommened the 2000 .01.01 because it has more screenpaks. ScreenPaks are the graphics you want and it will let you get more then 24 chracters. PLEASE SIGN MY GUESTBOOK!
