Refresh my memory(extract files from ps3 firmware)

[xPreatorianx]

Hey guys, I can't remember which tools to use to extract Core OS from a PUP file and then extract files from the CORE OS package. Can you guys tell me which programs to use? I've been searching but all the ones I've tried don't work.

First you unpkg, then you use cosunpkg on the "content" file created by unpkg.
If you want here's a little bash script I use to extract a pup, the devflash, and the coreos.

CWD=$(pwd)

if [ "x$1" == "x" ]; then
    echo "Easy script to speed up extracting a pup"
    echo "This extracts the pup, update_files,"
    echo "core_os, and the dev_flash folders"
    echo ""
    echo "   Usage : $0 <Update Filename>"
    echo ""
    exit
fi
rm -rf $1
./pupunpack $1.pup $1
mkdir ./$1/update_files

tar -xvf ./$1/update_files.tar -C ./$1/update_files

for f in ./$1/update_files/dev_flash*tar*; do
    ./unpkg $f "$(basename $f).tar"
done

for f in */content
do tar -xvf $f -C ./$1/update_files/
done

rm -rf *.tar

./unpkg ./$1/update_files/CORE_OS_PACKAGE.pkg ./$1/update_files/CORE_OS_PACKAGE
./cosunpkg ./$1/update_files/CORE_OS_PACKAGE/content ./$1/update_files/CORE_OS
rm -rf ./$1/update_files/CORE_OS_PACKAGE
set $1=
cd $CWD
