PSP Roms

its about PSP roms, what is the difference between .cso and .iso files ? ???

CSO is compressed ISO. Basically they're the same in terms of function, however CSO has been subjected to some form of compression algorithm so it takes up less storage space.

so u say that i its better to download .cso file, eight?

it depends. CSO takes up less storage space and also less time to download, however it executes slower. (i.e the PSP has to decompress the data before it can be executed) This could cause problems with games that place high demand on the PSP CPU, as decompression requires CPU cycles. In general, CSO is probably fine if you have the choice.also, try not to use shorthand such as 'u' ;)

thank you ^__^ and i'll try XP

Basically games that are around 1GB+ download .iso
small games are fine as .cso

You can also convert ISO and CSO backand forth, if you can download both an ISO or a CSO, then do the CSO to save Bandwidth, but be careful, CSOs can have things (like music, video) cut out! Then again if the ISO is in a RAR, then thats compressed to, just download, unrar then compress to CSO!

where can i get free psp roms?
