PSP's are super easy to mod these days regardless of the model. I use a 16GB micro SD card through an adapter I bought of of amazon for super cheap. I rip my PSP games and then put them on my memory stick and play them off of there. Load times are much better and my battery last alot longer. If you have any further questions don't be afraid to drop me a line.
here is a link to the adapter i was talking about.
