What do you mean opened with?

If you mean how do you play them then you play them the same as an ISO.

A CSO file is just a compressed ISO file to save space.

So place it in the ms0:/ISO folder and run from Game Menu Memory Stick.

you don't open them on a pc, they are run in the ISO folder on the psp

however, if the file association annoys you then go into a folder and go to file types and delete the association, but apart from the wmp iocon this has no other consequences for you

1.52>2.0>1.5>3.40 OE-A>3.71 M33-4
3.60>4.01 M33-2

make sure the name of the .CSO is not too long and doesn't contain '.'

also make sure they are in folder ms0:/ISO
