We hand-pick the homebrew that goes into our repository.
You can use your Wii to download homebrew, so you don't have to constantly put your SD Card in your computer to add homebrew.
The Open Shop Channel (our server for the Homebrew Browser) has homebrew that the HBB never had.
The Open Shop Channel is hosted and supported by members of RiiConnect24.
WiiDatabase is an excellent German site for up-to-date homebrew for Nintendo products. We have used some Wii homebrew that WiiDatabase hosts.
