Go to this guide HERE. Follow the directions for 3.52 M33-4 install which is close to the bottom of the guide.

You can skip the first part since you are already at 3.52 M33.

Use PSP ISO Compresser which you can get HERE.

Run the program and choose ISO to CSO load the ISO into it and it will convert it to CSO.
