I help with Klonoa 2, some of the grapics are messed up and The sound effects are missing. I have manged to fix the grapics but not the sound. The game starts to beep loadly at some points. I got the newest version 1.0.0 and I run Dark cloud and Ape escape 3 (AE3 allmost perfectly has some lagg issues) very good. I use the defult gsdx32-ssse3-r5350
