Hello there,

I have downloaded the ISOs of the two Battlefront games on PSP (Renegade Elite squadron). After extracting it? I found in the two archives the file which I think I am looking for : GMSND.FR.

However, the extension seems to be the language code, so I don't know how I can extract what's inside.

Could you help me ?

Here are the two files : https://we.tl/t-bIabh6T5SC

Thanks in advance.

Try Asura Engine Extractor. It's been ages since I used it but I remember right I got the sounds from it.

The only thing I can obtain with this tool is this (image attached), but I don't think these are audio files.

I don't have the files types described in the website.

If you scroll down, you'll find the RSCF chunk.



That's where the sound data are stored. However, you need to extract the RSCF file too to get the AT3 audio file inside. You can extract it with this script:

Code:

IDString "RSCF"
get RSCF_SZ long
get ZERO long
get UNK long
get ZERO long
get UNK2 long
get RSCF_SZ_2 long
getdstring RSCF_NAME 20
get FILES long
savepos TMP
xmath OFFSET "FILES * 0x0c   TMP"

for i = 0    get UNK3 long
   get UNK4 long
   get SIZE long
   string NAME p "%s\d.at3" RSCF_NAME i
   log NAME OFFSET SIZE
   math OFFSET   SIZE
next i
