Hi, newbie here, recently I tried to play "102 Dalmatians: Puppies to the Rescue" but I found out that the dreamcast version has one of the songs changed, so now I'm trying to replace the dreamcast ost for the og one that is used for pc and psx.

I have the og mp3 files from the pc version, but I'm stuck trying to extract the files from the dreamcast version.
I think that the "CARNIVAL.STR" is the file I'm looking for, but I have no idea how to open it nor replace it (and yes, those mp3 files are the ones found inside the files from the pc version)
Do someone now a little about how to modify str files?
I tried to search online but it seems that every game has a different file structure and formats, so couldn't find anything about this specific game

On the psx STR is a video file.. can you convert the STR file with this tool? https://github.com/m35/jpsxdec

I'm afraid not. It seems that this tool only lets me open disc images, I can't open the str directly

Ok, I just compressed the file into an iso and the tool shows the file, but it can't play it nor convert it

for ps1 str it is video, and for dreamcast it is audio
there is a converter in katana sdk

that is pretty useful to know, knowing this I found VGMSTREAM, and I managed to succesfully convert the str to wav, now I need to know a way to convert the wav (or any other audio format) back to str. I couldn't actually find the converter you mentioned

VuStream - look stream parametrs
MkStream - converter

I'm almost there! I successfully extracted the files and "repalced" the file with the new song, I only need to re-build the gdi rom. but the "Extract Re-Build GDI's" tool doesn't work on this game for some reason, so I used "GDI2DATA" to extract all the files, but I need another tool to rebuild the game, Is there another program that I can use?
