boot disk ps1 Coasters!!

[418]

I've been trying to find a boot disk that works on Amereican ps1's. I've looked on www.gamecopyworld.com and tried all of there disks for cdrwin and nero also. And still can't get them to work!! The only thing i see is a red screen that says (Please insert Playstation format disc) so I put the burned one in and nothing happens. I need help and my burner can use just about any program. Or if you know where i can ger a low priced boot disc please post it. thanks
