If you're talking about downloading the game, SoloBuggMaster, a) it's illegal and you shouldn't ask for them on any responsible forum and b) downloading games is dumb. The people who post them often don't rip them very well - you'll often have problems with downloaded games, if they work at all.
You can buy most Playstation games cheap on ebay or Amazon - I just took a quick look on ebay, and new, sealed copies of Chrono Cross are going for not much more than $10 US. If you want images, you can rip them yourself and make a much better job of it than any illegal game poster will.
I'd recommend ripping either to
CloneCD's .ccd/.img/.sub or
Alcohol's .mdf/.mds formats: these formats have descriptor files (necessary to read most Playstation game images properly) and include subcode from the CDs (necessary for playing protected games). In addition, those two applications were developed for ripping game CDs, which often don't have standard structures - Playstation game CDs certainly don't.
Alcohol do a free version of their Alcohol 52% application that will rip to both .ccd/.img/.sub and .mdf/.mds formats. It's very important when ripping to observe a few basic points: never rip at full speed (about 1/2 the maximum reading speed for your drive is favourite) and use a drive that reads non-standard formats well - as a rule of thumb, -RW drives usually read better than -ROM drives. An easy way to find whether a drive will rip a game Ok is to try playing the game from CD in it - if that's Ok, the drive is reading the CD properly.
