I have the ISO, using Daemon Tool won't work? or the PC can't read the music format, I searched on Japanese forum, they said you can change the music format using _inmm.dll but I don't know how to operate the program, there's no guide (or I don't understand). I guess I just should give up, It's not like I really want to play the game, but it's just I feel fidgety that I can't do anything about it.

Help I can't install the game, I already use locale emulator, using Windows 7 and XP but still can't run the game, every time I got this kind of error message, can anyone help me what's is the problem, and how can I fix it?
