Cannot overstate how useful this is going to be. Finally dolphin users will have a nice looking som, and this'll also help distributions that do not want to use CT-code. Amazing job and already a contender for code of the year in...January.

The code has been updated with correct right-alignment instead of padding zeros, and some slight latency improvements.

Really Nice Code. Will is be possible to change the color of it ?

Yes, you can do this by replacing 00010030 with 000100xx where xx is 00 for gray, 01 for red, 02 for white, etc. You can find the full color list here.

I updated a new version that hopefully fixes the bug (the code was using snprintf instead of swprintf), can you test it?
