ISO's are an exact image of the disc. CSO's are the ISO compressed to a smaller file. Depending what level of compression they used the smaller it is. Some uploaders don't test there compression so the game might get choppy.

hmmm i see. what sites test their compression and are good to get backups from?

Ive read that to play a cso, i would need to have a UMD in the psp as well. is this true?

If i convert the cso to an iso using "PSP ISO Compressor v1.4", would it be a 1:1 iso image of the game like it orignally was? or is it a (lossless compression), or whatever you call it when you can never convert it back to exactly what it originally was?

It's not the site but the uploader. I heard of an uploader named rickem over at mininova or darkside that tests everything before he ups it.

No you don't have to have a UMD in the drive as long as your UMD ISO mode is set to sony NP9660 no-umd

Yes you can convert it back but not as reliable as starting from the exact image.

whats the point of converting it back to a iso file if it is a lossless compression?

Do the graphics get worse when its compressed to cso?

Iso = Uncompressed image normal speed...
Cso = Compressed image, less space so could be laggy sometimes load longer compared to iso etc.

Personally i use cso because i dont see much of a difference of slowness etc however on bigger games e.g. gta i think its better to use iso so not to risk serious lag.

Fat PSP: 3.03 oe-c (will update when i have time :P)

the reason that you would want an iso would be if you had enough room on you mem stick, you wouldn't have as many potential problems. the value of a iso vs a umd is that you can have a bunch of iso's on a mem stick and don't have to carry around all your umd's.



I still play my wii, just not as much. Gave my PSP to my son.
