Is it possible to swap the "Original" BGM to a song of choice? It would make me enjoy the game more. The BGMs are contained in a folder called "sound" and are in ogg format. I've tried creating an ogg from an mp3 at 44100 Hz. After that, "original" doesn't play any music at all. So I tried 11025 Hz and the music plays, but it plays at about half speed and you can't really enjoy it. Can someone give me the proper converting options to make the game play a custom BGM at perfect speed?
