PSXIM is a software used to backup PSX CDs.
PSXIM is a simple program written in Python and PyGTK to back up PSX games into playable formats using cdrdao as a backend.
At the moment, PSXIM is only available for Linux and thare are no plans to make ports. These dependencies are included with the vast majority of Linux distributions out of the box.
PSXIM was developed under Ubuntu and it works very well there, but should also work for other distributions.
