I've finished work on a SSL tunnel + automatic patching tool for Wii games: save-nintendo-wifi.com/wii-nossl.html

Right now it only works with original discs but USB loaders should be able to implement this patch easily if someone wants to make a custom version that supports it. I've tested it with MKWii and it works, but SSBB is having some issues but I believe that might be because of my Wii's disc drive struggling with dual-layered discs. There's a manual patching method and that works with both games on Dolphin. Also note that it only patches main.dol, so on MKWii the Mario Kart Channel will probably still communicate encrypted.

Yeah, for MKWii your server already handles things well enough. This was mainly made for other games that use SSL-only servers like the download servers or encrypted Sake storage servers. The automatic patcher should also work in the future when custom servers get up and running.

Just a heads up, I switched the patcher loader to a different disc launcher that seems to have much higher compatibility. I've tested it and it works on both WFC games I have (MKW and SSBB).

BTW, what kind of OS is used for your server Wiimm? If it's not Windows I'm pretty sure you can implement the SSL tunnel on your server as well. That opens up logging for the download server and possibly many more.
