It should turn into an ISO which is PSP_GAME and UMD_DATA.bin in a WinRAR archive. Dont extract it that IS the ISO unextracted.

use a program called Iso Compressor to uncompress cso back to iso.

why do you want to uncompress a cso???
if the psp can play iso's and cso's and cso's are compressed iso's, why not just use cso's? they will just save you some space on the memory card, and other than the smaller file size they are the same as iso's right?

Actually, sometimes cso games are buggy. for example choppy movies or music. Most are fine tho.

There really isn't anyway to tell how the game will perform after converting from iso to cso, you just have to try and see. And if a game doesn't play well, one thing you can do is try converting back and forth between cso and iso, and see if it makes any difference.
