3.52 firmware??

I have 3.52 on my PSP and I've heard there's a new one. When I go to the update option under 'game', it says there is no need to update.

What's a fella to do?

you download it HERE

...and each game has a certain firmware to be played at.....the game in your PSP just happens to be 3.51 or less which is why it says you don't need an update even though theres a new one
