Things are indeed heating up on the homebrew scene. Looks like homebrew is coming to that PSP-3000 of yours. Davee has reported he has a working Kernel exploit on the way for the PSP-3000 / Ta88v3 Motherboards that will enable homebrew. Rather than rephrase what davee has posted, I’ll just quote it
HEN will [...]

True to his word MaTiAz has released Version 2 of his Hello World TIFF Exploit. This version works on PSP Slim units and we have reports from users that it even works on the PSP-3000! That’s a added bonus. As for the “bit of awesomeness” promised we have to wait just a little longer for [...]

MaTiaZ and Freeplay released another homebrew game for the PSP-3000. This time bringing us a nice side scrolling shoot-em up R-Type clone. This homebrew game requires a USA copy of Gripshift and a PSP-3000 with firmware 5.02 or less! (Not to mention some patience!)

Remember the video we posted about a working PSP-3000 hack using gripshift? The hack creator MaGiXien answered some questions on just why the Hen PSP-3000 Hack isn’t online yet. And when we are likely to see a PSP-3000 Hack. Here’s what MaGiXien from PSPGen.com had to say:
You all have in mind our video showing a [...]

The new blue service battery by Datel has been tried on the PSP-3000. So it puts the PSP-3000 into service mode. But results in just a flashing light and dead black screen. So its not REALLY a hack by Datel to allow users to flash custom firmware if that’s what you were thinking. It still [...]

brokencodes, of the Dark-AleX.org forums has gotten into part of the motherboard’s signing code.
What does this mean? It means we’re one step closer to hacking these buggers once and for all.
For now, its only a partial code but expect to see it cracked quite soon.
We’ll keep you updated.

But not by Dark~AleX. Guess who?
Datel out of all people have “cracked” the PSP-3000 and booted it with a new TOOL battery.
Compatible with the PSP-2000 and 3000, it goes for $19.99 in the UK and $29.99 in North America late this month.
BUT! There’s a catch. This battery doesn’t actually install CFW on your PSP.
From [...]

Homebrew developer Poison has released an update to CXMB his cfw plugin which allows users to load custom CTF  PSP themes. And all from the memory stick and not the flash memory so there’s no risk in bricking your PSP. This release add’s 5.00 M33 support, nothing else has changed.

Sony has responded to the issue concerning scanlines on the new PSP’s (see below).
SCEA
On some occasions, scan lines may appear on scenes where brightness changes drastically, due to the hardware features of the new LCD device on PSP-3000. Installed with this new LCD device, PSP-3000 offers more natural and vibrant colors on its screen, but [...]

One of the prominent features of the PSP-3000 is the updated screen giving more colours and less ghosting. Here’s one problem new PSP owners didn’t count on, scan-lines. This actually makes things look worse than the PSP-2000.
According to a thread at the PlayStation Forums, it is a widespread problem. Sony is currently looking into the [...]

The good news with the bad. Good news is the PSP-3000 ships with a TA-090 motherboard, the bad news its using a newer CPU and is its not booting up when used with a Pandora battery. Thus its Pandora proof and service mode can’t be accessed to flash custom firmware. Which suggests that more hardware [...]

Dark-Alex has had a look at a pre-release PSP-3000 in Spain and has confirmed what most of us thought, that the PSP-3000 system is Pandora proof at this stage. Universal unbricker / Despertar del Cementerio v7 doesn’t work. Dax comments that this is no doubt due to the fact that the PSP-3000 series must be [...]

Eurogamer had a hands on with the new PSP-3000. They have stated that the PSP-3000 will come with PSP Firmware 4.20 pre-loaded. This firmware will have a USB auto connect option that will automatically start charging the PSP in the XMB when a USB cable is inserted. Also a Colour Space setting has added in [...]
