After the recent discovery of the exploit that allows unsigned code to run on any PSP with firmwares 2.0 to 2.8, it was only a (short) matter of time before Sony launched yet another firmware update to fix the exploit, and now it’s here.

Usually, when Sony releases these “security patches”, the only thing that needs to be said is: “if you like your homebrew applications don’t update, if you don’t, you might as well do it”. However, this time, besides fixing a few bugs with some music files, and fixing the PSP so it won’t be exploited, Sony decided to increase the limit of the Memory Stick’s capacity that you use.

Since it’s release, and until now, the limit has always been 4GB, however, with this patch we lose that limit. It’s not confirmed yet whether they removed the limit altogether, or just increased it, however, if you like using your PSP a lot for viewing or hearing media, this latest patch is very tempting.

The word that is out, is that the most recent version of a program that decrypts the Sony PSP’s firmware in order to be able to fully emulate them with DevHook works with this latest firmware. So, although this doesn’t mean that you’ll be able to run Homebrew programs on the new firmware, it does mean that people with 1.50 Firmware will be able to load their PSP with the newest firmware, without installing, and have the ability to run ISO images of UMDs.

As a PSP owner, and media lover, I have to admit that it’s much more tempting to stick with my current firmware, rather than updating. However, if in a near future Sony makes the Memory Stick Duos that have over 4GB capacity affordable, it may cause more users to update. But I’m doubtful that will happen anytime soon, and even when it does come, by that time I’m pretty sure the homebrew community will have discovered a few other exploits by then.
