(also posted on 1src, read the discussions on 1src)

Hay, intresting update, makes the PSP a more mature product.

Here's what I can get with my clumsy Japanese. If you're Japanese, you can read it here:

Oh yeah, the update will be avaliable on July 27. The file you get now from the link is ver 1.52.
14MB on the MS needed and the file should be under /PSP/GAME/UPDATE
Wonder if this works on models not bought in Japan, can't find a warning that says you can't.
