Heres an Openbor Mod that should be compatible with the Dreamcast, Wii, Gp2x/wiz and PSP

Formally know as Sega Genesis Mega Brawler, Sega Brawlers Megamix is now the latest release since november. The roster now as 50+ characters, including new ones. One of the biggest updates of this mod is the new feature which is battle-mode. Once you start it, you will set in the hub stage, where there are 4 TVs. Hit them to change the channel of the stage shown, and walk into it to warp to that stage. Much thanks to Bloodbane for his help with this. Before playing the game, make sure to go to the options and set your controls for all the attack commands.
