if i remember correctly, mugen is closed source, so no. but either way mugen has been dead for several years now... but there is an open mugen-clone in development (http://www.sakirsoft.com/) that already has ports to windows, playstation3, psp, and of course linux. so i think we'll have to wait till it "gets done", to port it over to gp2x
patience young grasshopper, patience..
I've heard that Elecbyte have returned and working on a new version. It'd be great to have one with hi-res characters ; 2xsai - hqx filters .....sounds appetizing hmm
About os clone , ı'm sure it'll catch lots of interest once it has a quick port on gp2x. It may even fasten it's overall development process
