Yoshi's Island, Delfino freeze with Riivolution

(Searched for answers to this... couldn't really find anything)

I'm using Riivolution with Homebrew -- no Gecko, File Patch Code, or anything like that. Mostly everything works fine except I cannot play on Yoshi's Island or Delfino Plaza at all.

Yoshi's Island freezes exactly 51 seconds into the match, every single time.
Delfino Plaza freezes immediately as soon as it is selected.
Both of these are accompanied by a loud, awful "BEEEEEEEEEP" which requires me unplugging the Wii to get it to stop.

I do not have any custom textures on these stages, and I had this problem even before I put any -character- textures on. There is no custom music on them either so I have no idea what the problem is.

Strange..... YI changes season every 51 seconds so something related to it might be the cause of freezing.

What codes are you using on your Wii when this happens?

You may have to remove a stage related code for this to stop.

I don't have stage related codes on at all. It's just normal brawl but with textures and sound hacks.
