PS2 Utility Disc version 1.00/1.01 ????

[Kakarot]

I made a backup of my Ridge Racer 5 game.
Just to try this cool stuff. I understand that i can play the backup with the swap trick patch in combination with the PS2 Utility Disc version 1.00 or 1.01. (without a modchip).
But i can't find the PS2 Utility Disc version 1.00 or 1.01 zip file or ISO on the internet and no information about it.
Please help me to get the needed file and info.
