Im having problems installing ulauncher by modifying the iso of hitman blood money and swapping the disks at the menu etc.

I have a 39003 fat playstation 2.

Once I switch the disk with the modified copy and press to start the demo it just says to insert a ps1 or ps2 disk - it doesnt work.

Ive read it doesnt matter what quality disks are used, they are just cheap asda brand. Ive tried 3 different burns and none have worked.

Any ideas?

Thanks
