Trying to backup a PSX game... need some help

[mojo2185]

Ok, i've tried before, and failed. So i've decided to give this backing up PSX games a second whirl. Here's where i'm confused:
Is it possible to backup a PSX game, and play it on a PSX console that does not have a mod chip? I've read about "Boot methods" where you don't need a modchip, but i've tried some, and they didn't seem to work.
Can someone sort this out for me?

Thanks!
