Homebrew Problems with some emulators!

[ChrisDeweese]

I had just gotten another Wii and this one is giving me a bit of problems in the Homebrew department. When I try to run FCE Ultra GX, Snes9X GX, and VBAGX, they mostly give me a Code Dump error screen and every other load will be a freeze. Weirdly enough, Genesis Plus GX works without any problems. I'm not sure on what I should do.

Wii firmware: 4.3U
