PS1 on PSP help

[Rocksil]

Ive got some playstation games with me and i want to rip them into an iso format can anyone tell me the program they use to rip thier disk or say the best one i can use. plz?????:(

I think any ISO-Image software will do this job, as most PS1 games are pretty old and thus have no or only a fairly simple copy-protection.
I used Alcohol 120% for ripping my Tony Hawk's Skateboarding, but I really think pretty much any software is good enough.
By the way, Wikipedia has a list of programs which can produce ISO images: http://en.wikipedia.org/wiki/List_of_ISO_image_software
