For me the shader distortion is caused by the lack of color masking, and enabling the color mask fixes the problem (see my previous posts on the subject on page 4). However, I've noticed a framerate drop from the color mask option (only noticeable in the town, battles are still smooth).
Video should be working, though I've found that it works with some settings and not others. I haven't looked at it much. Voice does not work at all yet, and probably won't until SonicStage updates its audio decoding I think.
EDIT: Video works when "Only GE Graphics" is turned off. However, changing the game's resolution (for sharper polygons) only works when "Only GE Graphics" is turned on.
