PSX (PS-One) Burning without mod but with Yaroze?

[poserboy]

I know pretty much, that you need a mod chip to play burnt psx games, but what if you had the yaroze boot cd? I heard that you can play the games with the yaroze boot cd without modifying your psx. I wonder if it's true, but I know that there are hardware issues such as the laser isn't strong enough to read the burnt games and such. If anyone has info on yaroze, can you help me out? If you know where to get the cd image, that would help too. To sign up is around $450. Thanks!
