For those of you who have bought a new PSP-3000, there is some great news on the homebrew front. Thanks to PSP developer MaTiAz, a new savegame exploit has been found in the PSP game Gripshift £79.24 (US version) (US version only.) In a similar fashion to the GTA savegame exploit, this ‘bug’ has allowed the devloper to run unsigned code. It does not allow access to flash(0), so there is no hint of a downgrader becoming available, but it does mean that with some development work it should be possible to start playing homebrew games and applications on the PSP-3000 (PSP Brite.)
Copy the contents of MS_ROOT into the root of your memory stick (this will overwrite the first GripShift savegame slot).
Launch the US version of GripShift.
Load up the game (if it doesn’t autoload).
See your PSP run unsigned code.
It’ll autoexit after some time. You can use the home button to exit too if you’ve seen enough.
FAQ
—
Q: Will this allow downgrading?
A: No, because this is an usermode exploit and functions required to downgrade are
only available in kernel mode.
Q: Why the name?
A: Because the original exploit was found by overwriting the player name with “this is spartaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa”.
Q: Can/Will Sony block this?
A: Yes.
Q: I wanna make homebrew using the exploit. How?
A: Get FreePlay’s GS SDK: http://f6y.ath.cx/pspdev/sparta_sdk.zip
It has some constraints though, check the readme.
The Hello World was written with it.

News that will surely have Sony cursing at the next baord meeting, news comes in that Datel have developed a new battery that allows the new PSP-3000 into service mode, opening up the ability to customise the firmware the latest PSP can run.
The Datel device is called Lite Blue, and is going to retail for $29.99. Unless of course this is some elaborate April fools joke that has come late. Or early. In which case forget I mentioned it. But the news is up on Engadget, so I have a small amount of hope that its not a big wind up.
If this is true, I wonder what software was used to develop the new device, and how have they managed to get it out before the PSP homebrew community managed to develop a similar device?
News has come in that irShell is now available for PSP’s using custom firmware 5.00M33-3. There have been quite a few changes and enhancements made to this custom shell replacement, so you may want to hit the link at the bottom and grab yourself a download.
* Support Dark_AleX latest 5.00M33-3 CFWs. Users of original 5.00M33 & M33-2 should upgrade to M33-3 to avoid incompatibility issues. The latest Popsloader 5.00 is also supported.
* An Infra-Red learning remote is added for PSP Phat. You no longer need to hunt pronto codes for your appliances. Just point your remote unit at the PSP and it will learn the iR code. It is available under higher firmwares and not fw 1.5 mode. Refer to the Release Note for usage details.
* The nethostfs connection handling has been redesigned to be more robust. However, iR Shell 4.7 and onwards can only connect to the new nethostfs PC server v2.1. Make sure you’ve updated the nethostfs PC server.
* Enhance UMD/ISO game compatibility via nethostfs MAX mode. Most previous failed games will probably work.
* Usbhostfs & nethostfs host redirection under XMB has returned.
* The Adhoc PC connection for nethostfs was broken since fw 3.71. This feature has been brought back for PSP Phat.
* Enhance the HTML Plugin (by Dark_AleX) to allow direct launching of flash games with extension SWF.
