Mugen, A game that let's you make your own 2-d Fighting game, I FINALLY got it working for windows VISTA. My characters are, Ryu, Z-Akuma, Dan, Vega, M.bison, Violent-ken, and Guile. I have three stages. M.bisons stage, from Capcom vs. konami, A staircase that lumes in a spiral, downwards, and upwards, depending on which direction we walk, And one from megaman.
If anyone has M.u.g.e.n Feel free to ask me where, i got my characters.
