I always wanted to port MUGEN to Mac. So far I have ported 3 MUGEN games to Mac OS X.
The original MUGEN 1.0 distribution. Comes with no characters, you must find your own.
A stable and fast MUGEN build. Comes with many characters that are added personally, because I felt that a game labeled “Tournament” needed this.
A good fighter with characters from the show Dragon Ball Z. Comes with many different characters, but is unmodifiable and can only hold the default characters. Still, the characters built-in are very good and fair, and there are more than 100 different characters.
HUGE screenpack, with almost too many character spaces.
The well known edit tool is finally on Mac. However, you must choose the MUGEN EXE from inside the MUGEN X game or a MUGEN Windows EXE.
Fighter Factory 3 is a MUGEN character editor/creator. I ported this to Mac to create my own character creations, and to fix others to work.
