anyone knows of MKW hacks with ISO patchers which include custom characters and 2. The hack that I know does feature two custom characters and an ISO Patcher is restricted to online play with friends, which makes it practically useless to me. However, besides one hack, there are no MKW hacks with ISO patchers which include custom characters. Hi everyone! I've been installing a few Mario Kart Wii hacks recently, but only custom track distributions because those were the only hacks which came with ISO patchers.
