I believe that is the result of the ntsc color fix not being done to your chip.
When I load a NTSC PSone game it only takes about 2/3 of the screen.Its the bottom thats missing.
As far as booting goes if you system is on and at the browser screen then inserting the disc and closing the tray will boot. If you have a game already in and loaded then you must reset the system to initialize booting of the disc. It is like this with any origianl game as well.
