I have translated the Ultimate Popstation GUI Version 1.0.
All the credits go to them(from the original post):

-Support for Single Disc games.
-Support for Multi Disc games.
-Ability to change how your PS1 game looks in the XMB!
-Ability to set Compression Levels per Disc
-Ability to set more than one Game Code per Disc
I tested this with Metal Gear Solid (Multi-Disc) and Spyro (Single-Disc) so hopefully it completely works.... If you do so happen to find a bug in this please feel free to tell me in this thread.
