Hello everybody! Here's an unusual task to crack. The Microsoft Game "Deadly Tide" from 1996 is a rail shooter. All levels are packed in *.l96 files which contain all files from the level. What I'm after is the music which I think is quite nice in an oldschool kind of sense. If you import a plain L96 file as 22kHz 8bit mono PCM you can see that the level music is implemented somewhere in-between the rest of the files. It seems to consist of blocks of 0x4000 bytes. I know that there's a soundtrack out there but I'd like to have the stream from the original files to compare them to the soundtrack. Now, I don't know how complicated it is to reverse this format - you tell me. Here are some samples: http://*USE_ANOTHER_FILEHOSTING*/cdc2d8e ... samples.7z Thanks for your consideration.

goto 0x40 get OFFSET long get BNAME basename get FSIZE asize do goto OFFSET get ID1 long get ID2 long get SIZE long savepos OFFSET string NAME p= "%s_%s_%s" BNAME ID2 ID1 log NAME OFFSET SIZE math OFFSET += SIZE while OFFSET < FSIZE
The problem with this is that sometimes ID2 holds the SIZE - 4 but I can't figure out how this is determined. In other times, the start offset is different. I suspect the format to be not extremely complicated to crack but I have too little experience. So... thanks for any help - there are already two games that use this format!
goto 0x40 get OFFSET long get BNAME basename get FSIZE asize for i = 1 goto OFFSET get ID1 long if ID1 == 0x826 get ID2 long elif ID1 == 0x829 else print "unknown ID %ID1%. Aborting." cleanexit endif get SIZE long savepos OFFSET string NAME p= "%s_%s_%s" BNAME i ID1 log NAME OFFSET SIZE math OFFSET += SIZE if OFFSET >= FSIZE break endif next i
The new problem is that there are blocks without marker or block size... If this problem can be solved, the format may be cracked! This would be SO cool - the music is really nice! Here's another .l95 sample: http://*USE_ANOTHER_FILEHOSTING*/6ed75d4 ... LEVEL02.7z
