hi johnmph.

Im trying to use you exellent work in my psp shell, but unfortunatly it seems to have some problems with a lot of my 7z packages. Sometime It unzip only 128ko, the size of the buffer and sometime more. Here is a package exemple if you want to take a look :

http://mydedibox.homelinux.com/Orbz-0.3.7z

http://mydedibox.homelinux.com/pspatari-v1.0.5.7z

I hope that you will take a look and that it will help to improve this cool lib.

Is there another simple extracting lib available around ?
