Firstly if you can only use Nero.... then you will need to get a new burner at some stage when you come across games that need patching (and there are a fare old few of them).

Personnaly i am surprised that you can only use Nero!

Secondly it sounds like your PS One has been moded badly, by this i mean that the installer has either used the incorrect diagram or the chip was programmed with the wrong code, or even the conections have been badly soldered. Get this part sorted out first!

If you dont play imported games then you wont need the "Boot" disc!

Hope this helps.
