I have tried to convert image files in three formats, .iso, ccd/img/sub, and bin/cue.
.iso and .ccd/.img/.sub extension files may contain some problems, such as no sound at FMV, the game would not be loaded, and there might be some graphic glitches.
So, i try to convert those image files into .bin/.cue and now they works perfectly. So, if your image files that has been converted cannot work properly, try to convert it into .bin/.cue. I converted them by using MagicIso, just choose the Tools tool strip menu and choose convert, and the rest i assume you can do it by yourself.
