As long as we don't discuss where to get ROMs, it's all good, right? There's lots of non-emulation stuff, like Wii Linux (very, very early), MFE (media center program), Wii Paint (basically a demo), I believe a port of Quake (might be 2 or 3), and quite a bit more. It's hard to find a site that focuses on all of the homebrew stuff, it's usually one thing or the other. Nintendo can potentially block this from working, but they certainly will not brick your Wii (they even repair Wiis with modchips in them that have the SSBB problems, for free, and send you back your chip [and a note telling you that you're a dirty pirate], with a new DVD-ROM). Most of this stuff is available do to something call the Trucha Signer, which allows you to sign content with a bugged "common key" so it will run on the Wii without modification. If homebrew using Trucha ever does get blocked, then it's 100% Datel's fault (boycott this company), because they used the Trucha exploit for the Wii FreeLoader.
