 As a result, games like "Dylan Dog Horror Luna Park" show IO errors while reading data from the CD. Unfortunately, this is not the only problem of this game, so Dylan Dog fans will have to wait further.
 Maybe some other programs suffer of this problem, and I will strongly appreciate if anyone finds some.

+fixed BACKBUFFER surface attributes in direct (not emulated) mode: Rayman 2 playable again
