Hey I recently found out a 2-d fight simulation program call m.u.g.e.n. I was wondering where do you download it? I search everywhere, even google but not even a simple link.
I heard the main site died long ago, but some sites still host the file. I'll look for you, I think I remember where I read that.
I think this is the right one, I think you can only add sprites and stages with this, but there are add-ons out there to code and such, I'll provide all links.
All other MUGEN: http://randomselect.i-xcell.com/ On the side bar under downloads, click on Linux and the download should start, same with DOS version.
