I'm releasing it as it is for I have no interest in the Mugen any more. If anybody wants to work on it, you have my thanks. I was working on a X-Seven arena as well but never made it to coding and importing. Enjoy.
I don't think it's solely your fault. I think its partially Pandas fault too. We asked Pandas if he'd sprite them and he became busy, you offered then just never came through, that's worse in my opinion but w/e.
