lol, why does Haggar always look like he's doing nasty things while grappling ? ;D
Beside this, nice stuff. I just thought it was an OpenBOR module but it's a rom-hack... didn't try it as for 4 players I'd really suggest Vendetta or Crime Fighters (even if they have a slightly different gameplay).
Also those lifebars are taking 50% of screen (with the 3rd player's score above the time panel), but I guess it could be a pain for modders to resize them as I saw in some OpenBOR modules (with the lifebars above the players/enemies)...
Out of curiousity: how many mods/hacks/ports/clones of FF are around there? That would be interesting to know, just to take account of them.
