Rock band: Unplugged (PSP) BEATMATCH.STR archives

[Game Ripper]

Hello everyone, I have some custom archive format on my hands and I'd really appreciate any help I can get with getting it split into individual contained files.
This BEATMATCH.STR thing is definitely uncompressed and probably contains all the data associated with each song: scripts and other control files, notes, some text docs and so on. Every song has its own folder in "Music" directory and 3 files can always be found there: playable stereo preview track with an AT3+ header, headerless multichannel audio stream (possibly Atrac3 too) & finally BEATMATCH.STR.

Here you can find a few example files, I hope they prove useful.

Best regards, Game Ripper.

Don't know what data is that in the extracted files:

Code: Select all

get DUMMY long  # 1
get DUMMY long
do
    padding 0x40
    get OFFSET long
    get SIZE long
    get END_OFFSET long
    if SIZE != 0
        log "" OFFSET SIZE
    endif
while OFFSET != 0
