Was pretty bored last night and fired up the old Wii and noticed I only had r185 of Desmume Wii.
I had never compiled a source code before so I decided to learn a crash course and grab the latest svn from Google Code.
It had a few code bugs that stopped it compiling but with a bit of trial and error i have managed to create a working .dol.
Grab it here: DeSmuME_Wii_r230.7z
And remember any issues you find to report to the coders not me :)
