PS2 image CSO compression on Linux with MaxCSO
CSO was originally only intended for smaller PS1/PSP disc images, so a different version can be compiled to support the larger DVD based images that PS2 games are usually distributed on.
sudo apt-get install git-core build-essential liblz4-dev libuv1-dev zlib1g-dev git clone https://github.com/unknownbrackets/maxcso.git cd maxcso make sudo make install
Now that maxcso has been compiled and installed, simply compress all iso images in a directory via:
for i in *.iso; do maxcso "$i"; done
