Wario-Man on Character Selection Menu

[That BattleToad PSA Guy]

I have a hack for Wario-Man, but I can't access it on the Brawl+ Selection Screen. I'm thinking I have to get him on the menu, but I don't know how.

And to make matters worse, I can't even ACCESS the Selection Screen. It'll make this annoying buzzing sound that'll make me have to turn off my Wii.

What do I do?
