I would like to play Really? Really! DS, but since I don't know enough Japanese (particularly Kanji), I sorta need the voiceovers to help me out. The problem is, the voiceovers for this game are really weak. At max volume, I can barely hear the voices, but the opening song was so loud I took off my earphones in panic when it played. I read up a few DS ROM hacking guides aimed at sounds, but they don't seem to be applicable for my goal. Using Nitro Explorer 2, I extracted the sound.sdat file. Then I used the sdattool to extract its contents. Sadly, the sdat file only contains the BGMs and SEs, not the voices. Based on the filenames, at least. (i.e. wave_bgm.swar, wave_sePUZZLE.swar) Looking at the other files in the ROM, I found a file named vss.bin. It's the largest file in the ROM (130MB), so I think MAYBE that's where the voice data are stored? I read somewhere that .bin files are not "universal" (there is no one way of decoding them), so I'm kinda stuck. Is it possible to increase the volume of just the voice data? I hope someone with ROM hacking experience can provide some input.
