Newbie here trying to start hacking but have questions

[vegareaper]

Well I'm new to the whole modding thing. I bought a wii over the weekend and softmodded it. downloaded most of the games and i am currently using Configurable USB Loader to launch iso's i downloaded of romulation. Is there a way to hack those iso's so that i can add characters to the roster and if so what would be the best way to do it? if anyone has a tutorial that would be appreciated.

Well, you can use WiiScrubber to patch the files in the vault into the ISO itself. Or, you can make a GCT File in the Codes folders, and place all the downloaded files much like other Gecko Users. You'd spend less time if you could figure out how to do the later.
