I was under the impression the core pack came with a 32mb mem stick, I was wrong

So I gotta wait for my 2gb to arrive.
Anyway its a TA-82 and 2.71, is this page accurate in the downgrade process?

As for the PSP its still a good looking piece of hardware, bright screen, no dead pixels. It has definitely improved feature wise since I sold my old one. That was a launch psp though and was good for nothing but lumines.
