Okay I figured it out, the thread is correct about downloading the RPG Maker XP RTP, and the reason we have the missing audio files is because it is in the RTP folder. Wherever you downloaded the RTP it makes a folder called Standard, and in that folder you have Audio with all the common sound effects you get with RPG Maker XP. All you need to do is copy those common files over into the Opala Audio folder, and you won't have all the missing files like we used to be missing. There probably is an easier way in the RTP help thread but I can't post links as of now :SI'm also having a issue with the BGM files aswell and don't know any way to fix it. This is the only game out the three I'm having an issue playing and I would love to play this one aswell. Does anyone effect way to fix the BGM issue?
