openMUGEN - a free open source version of the famed (but dead) fighting engine known as M.U.G.E.N. has slowly but surely made some amazing progress. Its not ready for a portage yet.. but its somthing to keep in mind :) . It seems to be written in SDL and is much improved graphically over the origonal MUGEN. It seems to be able to use the old character formatts from the commercial MUGEN (at least with once character). Download the Demo and play around with it.
the source is located somewhere around here.
