Hi ThatNoobyGuy. The issue with your request is that the majority of existing/available tools for making Wii Channels contain copyrighted code from Nintendo, and thus are not discussable within the WiiBrew.org community--its strictly against community policy to use Nintendo code to create software.
WiiBrew.org is very anti-piracy, and insists on only using and supplying applications and tools that do not contain copyrighted code. This protects the WiiBrew.org tools and community from copyright infringment concerns and potential lawsuits.
The few channels that are available thru WiiBrew.org, for things like the SNES, NES, and GBA emulators, come from custom generated code made by members of the community (well, mostly Tantric). That's why the offerings here may not appear as complete as other sites, but they won't get you sued. The positive side to all this (and its a big positive), is that WiiBrew.org channels won't brick your Wii.
