if someone needs G1l extract your files and converts them to "wav" or "mp3" this there a simple tutorial through the help of AlphaTwentyThree.
PS: I did the process in the "BGMLink.g1l" Dynasty Warriors 7 Ps3 but I think it can be used in other files G1l.
1-EXTRACT THE FILES AUDIO "BGMLink.g1l" USING THE PROGRAM "SKYS CONSOLE FILE SCANNER"
OR "Dragon Unpacker 5".
NOTE: WITH "SKYS CSONSOLE FILE SCANNER" WERE PRODUCED MORE THAN 70 WAV FILES, BUT THE TRUTH IS "AT3", WHILE THE "GAME EXTRACTOR" JUST BEEN GENERATED 50 WAV FILES.
2-MODIFY THE EXTENT OF ALL FILES "WAV" FOR "AT3" USING THE PROGRAM "buck-rename" IN EXTENSION OPTION CHOOSE "FIXED" AND SPECIFY THE NAME OF EXTENSION IN FRONT, SO "at3".
3 - NOW JUST CONVERT FILES "at3" FOR "aa3" and play them WITH THE PROGRAM "SoundForge" OR "kmplayer" AND IF YOU WISH CAN SAVE THEM AS "wav" or "mp3".
NOTE: If someone does not convert from "at3" to "aa3" let me know that I send the script quickbms.
