2.0 update works on US versions

[sarb]

You can download the new japanese 2.0 firmware update .... and it will apply fine to the US version as well. I just moved it to the memory stick and installed it the same way i did the last one.

Just put it in /PSP/GAME/UPDATE
(all caps are important)

have fun!

How would this relate in any way to a bunch of people that could have told you that before it came out and who are not going to update for obvious reasons

You can use it or ignore it as you see fit.

While still personally interested in the direction homebrew could go on the PSP, and some of the technical aspects... I missed the boat and hit 1.51 on my PSP literally 3-4 days before 1.5 was hacked. :P

Plus the 2.0 wallpaper feature is pretty wicked. It will scale and crop images for you based on how you are currently viewing an image. :)
