Hans Brofeldt have been making a wonderful job for several years now.
I first knew about his website in 2007 when he first contacted me because of my left hand transcriptions, and later because of a challenge concerning making Beethoven's Allegretto (from the 7th Symphony) for the left hand alone which I made and dedicated to him.
Some time ago I sent him some updates which are still missing in the webpage, I shall contact him again to check if everything is fine with him these days.
Best
