Sony today released a firmware update for all US PSPs. The update, which contains firmware version 1.5.1, requires at least 14MB of free space on your Memory Stick. To access the update you need a Wi-Fi internet connection, then simply go to the Network Update option which is at the top of the Settings menu.

You can also download the update via computer, then transfer it onto the PSP's Memory Stick.

So, any idea what changes are in this firmware update?

That is one beefy update. That's half the included memory stick, pretty unacceptable.

yea but you can delete it after you update it so its not a big deal for those who are going to update.

i dont have a wireless router so I downloaded it from the link on this site and tried running it on my psp (i put it in the games folder) but when i tried running it, it gave me a error and wouldn't run. and I read around to find out this is just a security fix for those who are wondering whats on it.. u wont notice anything different, supposed to be the same one as the jap update.

It says it adds revisions to strengthen security but I haven't installed it.

I'm not going to install this. If it ain't broke, why fix it. Anyways this might eliminate any chances of homebrew/emulator stuff on my psp.

When you boot after putting it on the memory sticfk, does it flash the eprom in the PSP or something like that? The "computer" d/l link is only the eboot.pbp, and no readme. Obviously it's lame to have 14MB sitting permanently on a 32MB memory stick!! Flash/delete is the way to go... I'm assuming Sony was smart enough to implement this. -Pie

once your done updating the psp u can remove the 14mb installation file. oh yeah in order to update the psp u must have it pluged up to the ac adapter.

Chris if u have the american version of the psp u already can't run emulators.

Mamalayy: true, but in the future somebody might find a flaw in 1.5. With that in mind I don't want to upgrade if I don't have to just yet. my 2 cents.
