An old video gameplay by Ruivo:
agree with that, even if half of that "professional" belongs to the respective authors of the graphics. good coding though, I only heard bad news about something like that (a beat'em'up in MUGEN) being glitchy or limited, but I think that if only Elecbyte made it possible with an easy way... there could be a very good competitor to OpenBOR, honestly. I wish someday MUGEN source will be open, MUGEN + OpenBOR can be a dream
