Damn, I thought I was going to beat you to the solution. Seem I was a few hours too late.
However, I have only tried and solved one game so far and that just happens to be (insert fanfare here) Akumajou Dracula X Chi no Rondo
. However, strangely enough the voice during the intro sequence seem to be german..?
The original problem was that Daemon tools couldn't handle MP3's, right? So I converted them (could have used your batch file there) to wave. However, DTools was still complaining and the problem this time was that the sample rate was too low. So then I had to convert the files to 44.100 Hz (aka CD quality). I used Audacity for all these conversions by the way.
After that my cue file, referencing wav files was accepted and the game played just fine in Ootake.
Now, I want your batch files. Do you need anything from me?
