Hehe, was just not ideal if you always scroll just way down. Now it's gonna get pretty bad, considering one will look for the latest answer somewhere in the middle of all the comments.

But you don't know what it does exactly, right? Looking at Rance IV, it's definitely related to the music, considering that _inmm.ini lists the bgm in .mp3 form. Still, if it's really because of it there must be reasons why. Like, Toshin Toshi and Rance III were released for System 3.5 (Windows 95) and that's why there are issues (considering it's System 3.9) or something like that. Their release dates are also closer together, so at that time they did XYZ. Maybe it's an issue with System porting, Rance IV being 2.0 originally and Toshin Toshi being 1.0 (same with Rance III)? Meh, will probably test some more to see whether the errors really disappeared.
