Extract game

How to extract a PS1 game from my PS1 CD to be played in my PSP 3001?

 

Uh... right.

Just follow everything on this tutorial: http://pspslimhacks.com/psp-tutorials/converting-psone-games-to-psp-eboots-psx-to-psp/
That covers the entire process from ripping the CD to putting it on your PSP.

 

Thanks...Do I do the same thing for PS2 iso files too?

 

I am not sure if it is possible to play PS2 games on a PSP...

However, if that is possible, you can use most of Step 1 in the guide below to rip the PS2 disc. Don't do anything below the third picture.

Thanks...Lastly,how do I make PS1 games playable in my PSP when I download it from romulation?

 

That was included in the guide I linked you to first.

Find the picture below in the guide and start reading a little above that.
