Didn't work for me. It says ahbprot is not enabled. Everything else works though. I just recently updated my Wii with Modmii and installed Homebrew channel, Wiimc, Cfg Loader and a lot of other stuff and their channels, but with this Snes9x channel installer i get that message and it won't install. Snes9x works fine when launched from homebrew.
I'm on 4.2e with everything rehacked just couple days ago and installed every ios and cios Modmii Wizard offered.
