PSP firmware guide

If [Fluke]‘s comment is correct, then the Sony PSP 2.01 firmware is already in the wild. Here is a handy Hack-A-Day guide so you can tell at a glance whether you should upgrade your firmware. All you have to do is compare the firmware version number to the previous release:

  • If the first digit has changed (1.5 -> 2.0) then Sony has gotten around to adding a major feature that should have been available since the product’s initial release (web browser). Thanks to the magic of firmware upgrades manufacturers can leave lots of features out of product launches.

  • If the second digit has changed (1.0 -> 1.5) then Sony has released the hardware in your country. The games aren’t region-locked so there is really no reason for the launch delay.

  • If the third digit has changed (2.00 -> 2.01) then Sony has decided that you’ve been having entirely too much fun with your hardware without their help and are determined to re-break it.


  1. Does this mark the first color photograph on hack-a-day’s front page? I’m not entrely sure what this post means. I don’t see a hack at all. It’s just a description explaining what sony (or anybody) might mean with its firmware version numbering.

  2. Naa. It has happend before. Heck there are at least 1 or 2 other color pictures there right now. And those are animated. Please nothing to worry about.

    Wait, I think adblock is disabled.

  3. heh heh, nice Hal

    We’ve had frontpage color before: Wallpaper posts, defcon, anniversary, toorcon. I’ve started throwing color on these random posts to differentiate them from the hack of the day which are grayscale.

  5. In that case, never mind my insanity…

    fast loader kicks ass

  10. raytard says:

    basically dont get 2.01 under any curcumstances right now. 2.0 has been hacked,a nd its safe to get 2.0 (same with everythign less than 2.0) refer to for information on all of this. (as well as homebrew and downgraders. has some shady software, and movies/shows preformatted for your psp, incase ouve ever wanted to watch the rndom southpark episodes on your psp, or if u just want free widescreen mp4 movies.

    any one tried hooking a webcam up to a psp saw where some one tried it but it kinda looked fake

  12. Bob says:

    Anyone thinking of getting a PSP mostly/entirely for the hacking/emulation/homebrew should really think about buying a GP2X instead (gp32 successor). I’m definetely getting one.

    It’s almost totally open (Linux), has a builtin media player that does XviD, DivX etc movies/slideshows (with hardware scaling) + mp3/ogg, anyone can dev for it with standard F/OSS tools at no cost and the company *actively supports you doing so* unlike Sony who constantly try to fuck you over. Plus it’s considerably cheaper and takes standard SD cards rather than expensive UMD / memory stick. Quake, UAE, a PCEngine emu, Visual Boy Advance etc have all been ported already and it’s not even on general sale just yet! – Official site – UK distributor – US distributor
