Finally nabbed a brand new 2.71 PSP so I need a LIL help to get started. 1) Website to buy cheap 4 GIG mem cards, I prefer a place with real fast shipping if possible. Any reliable legit suggestions? And what type should I nab? Kingston? Sony? 2)How to downgrade. Where are the DOWNGRADERS? The semi-newbs Guide to downgrading and upgrading your PSP. I would GREATLY appreciate any info, thanks fellas.
