First, hello all. I'm glad to see these forums back up and running, and appreciate all that you guys do here at gbatemp. As for my question, I've been trying to extract the voice clips out of Tokimeki Memorial: Girl's Side 1st Love Plus. I'm 99% sure they're packed in a file called "voice.opp," since they're not in the .sdat file. However, I've searched everywhere, and I can't even find any mention of .opp files in DS Games. Does anyone here know of a way to extract the sound files from it? The programs I've seen that are normally used with audio, such as VGMTrans and Crystal Tile 2, don't work. It might be a custom format, but I have no idea where to start if so. Forgive me if this is a simple question, but I have little experience in hacking/unpacking DS games. Thanks!
