I don't have anything yet, please don't expect anything soon.
Right now, I'm only tricking Sudomemo into thinking a DSi is connecting rather than my PC.
The only reason I'm doing this is since he added some prevention mechanisms against PC connections (partially just the WFC server he has to use now), and I didn't want to feel prevented. :-(
Hey, I'm just glad nds-constrain't was found, and that session duplication is no more.
I'll probably post some information soon or make a simple proxy at some point, but I probably won't make a GUI since I don't imagine Sudofox would be happy with random people connecting without a DSi.
