On your last blog you made, that would be impossible to play Scratch files on your Wii, because the Flash/SWF version of the Scratch for the (.sb3) file emulator is probably in version 17 or 14, which equals to being in ActionScript 3.0. The (.sb2) file format won't work either because once again is the Scratch emulator for the (.sb2) and (.sb3) file which is the (.swf) file which is converted in that part.
