I just want to PLAY Spyro3!!!

[Addicted]

History: I have a PSX which was chipped about a year ago. I have no idea what version chip is has. I also do not have a CD Burner, but I might have limited access to one.

Problem: I bought Spyro3 this weekend, and I get the protected screen saying my PSX has been modified. I just want to PLAY it, I am not interested in making a backup.
What can I do!!!???
