The problem is two-fold.

1. Pixels are arranged horizontally
2. Blue pixels are much darker on the 3000

Given these findings, the problem appears to be 100% hardware-based. So now the question is, how is it possible that Sony didn't see this problem coming? Literally? [Logic Sunrise via Maxconsole]

There are dozens of guides online that show you how to get custom firmware onto your PSP in as many different ways. This is the method I found to be the easiest, combining tips from sites like PSP Slim Hacks and Code Retard. Note that this is customized for the PSP Slim, which is the only PSP you can go out to stores and buy, but most of these steps will be the same for the older PSP. I started the process with a PSP running 3.71 firmware, but it should much the same on other versions.

1) Buy a PSP MAX Power TOOL SLIM battery. Trust me. Unless you have a friend who already hacked their PSP and has a service mode battery of their own, this is the easiest solution. There are ways of modifying your current battery to enable service mode on your PSP, but the time spent doing that is much better spent doing ANYTHING else. Buy this for $25 and wait for it to come in the mail.

Update: Reader Wrocky found this $10 version that supposedly does the same thing. Buy it here at Dealextreme. We haven't personally tested it, but if it works, it works! The only downside is that it's made for the original PSP so will stick out of your battery case if you have a PSP Slim. Since you'll only be using this once, that's not a big deal.

2) Make sure you have at least a 256MB Memory Stick and a USB to miniUSB cable to connect your PSP to your computer running a version of Windows XP. I tried this on Vista but it kept erroring out on various parts of the process.

3) Charge your current (normal) battery as well as the MAX Power to full.

4) Download this file here, as linked to from this guide here. Extract the file to your desktop (remember, Windows XP machine).

5) Connect your PSP to your computer via the USB cable and setting it in "USB mode". Use the standard battery for this. If you have any important files on your memory card, back that up to a folder on your computer first.

6) Run the "START.exe" file from the package you extracted. Follow the instructions there. Once this is done, you'll have what's called a "Magic Memory Card", which is used to replace the standard firmware with a customized one. You'll have to pop your memory card in and out as the program tells you during the process. Follow the instructions until it tells you that you're done, then disconnect your PSP and turn it off.

7) Take out your normal battery, but don't put in your MAX Power battery just yet. Hold the L button (the left shoulder button) while inserting in the MAX Power battery. Make sure it's secure and won't fall out fall out while you're putting the battery cover back on.

8) Once the PSP is on (you might have to flip the power toggle) you may see a black screen with white text, or you may see nothing at all—I saw a completely blank screen for some reason. Either way, the power light on your PSP should be green to show that the unit's powered on. To install the firmware, press the X button. You should see the Memory Stick light on the left of your PSP flash with activity. When this is done, the PSP will shut itself off. Congrats! Now you have version 3.71 m33. But you're not done.

9) To upgrade this to version 4.01 (the latest hacked release as of this writing), download these files. First, the official 4.01 firmware. Then, the hacked 4.01 m33 and also 4.01 m33-2. That not a typo, by the way: Those file names are actually backwards and m33 is actually m33-2. Keep this in mind.

10) Extract all 3 files into their own directories. The 401-m332 folder (which should actually be the m33 update and not the m33-2 update) should have a folder called UPDATE under it. The Now, place the 401.PBP file (the official 4.01 firmware file) into the 401-m33 UPDATE. All this is going on on your PC's hard drive, not the PSP.

11) Then connect your PSP to your PC again (put the normal battery back), enable USB mode and copy the entire UPDATE folder from your PC onto /PSP/GAME/ onto your PSP's memory card.

12) On your PSP, exit USB mode, go to the Game and then Memory Stick, and run the PSP Update. Follow the instructions on screen, and you should have a PSP running 4.01 m33.

13) Now, connect your PSP to your computer using USB mode, delete the UPDATE folder under /PSP/GAME from your PSP, and copy over the UPDATE folder that belongs to the 401m33-2 file from your PC onto the PSP. Then go to the Game section and run this update on your PSP. You don't need the official 4.01 firmware in your UPDATE folder for this. Woohoo, you're finished.

Are you ready to get some homebrew going? Hit up PSP Hacks for a big list of applications you can run, including web apps, radio apps, Sudoku and even emulators. For obvious reasons, we're not going to link you to actual ROMs to run on an SNES emulator, but you can find those in the usual places you get ROMs. There are several SNES emulators to choose from, but this SNES emulator runs particularly well on the PSP, lending itself to old school gaming on the go.

Although a side effect of homebrew is that you can run pirated PSP games on your PSP, that's being pretty naughty and isn't something we encourage. The fact that a lot of people are doing this is contributing to (according to Sony) the lack of good games for the platform, which hurts everybody. Try not do to this.

What you can do is rip your old PS1 games and play THOSE on your PSP without waiting for an official release and having to pay Sony again for something you already own. Another idea when you're going on vacation is to get a 16GB Memory Stick and load all the PSP games you own onto it so you don't have to carry around so many UMDs. In order to rip PS1 games, you'll need a program like ISOBuster (there are others as well) that can take your disc and create an "image" of it on your hard drive, which is just a file representing the contents of the CD. You then plug those files into a program called PSX eBoot Creator to make it suitable for your PSP. The file and instructions on how to use it can be found here. You don't need a separate emulator once you have the eBoot file, but you do need plenty of space on your Memory Stick (1GB is probably only enough to hold a couple small games or one large one).

Thanks: We wanted to thank all the hard work that the PSP community—which includes PSP Slim Hacks and Code Retard which we got much help installing this from.

Did you like this How To tutorial? The point was to give you the easiest path from start to finish, even if it required you to spend money on purchasing something. Your time is valuable, which means you don't want to spend hours solving something yourself when it can easily be bypassed with a few dollars. What do you want to see a How To on?

• 1 Million new PSPs were sold in Japan in around two months. This first point got us curious as to why the PSP was doing so well. Was it because of the redesign, which lead to 250k sales in four days, or has it actually become time (thanks to various factors listed below) for the PSP to catch up, if not surpass, the Nintendo DS. This point alone wouldn't make for a strong argument, but we've found seven more.

• Sales figures for PSPs are going up, sales figures for DS Lites are going down (in Japan). According to the Japanese sales charts Kotaku loves to drool over, the last four weeks for the DS looked like this: 76243, 78552, 78854, 76069. The last four weeks for the PSP looked like this: 59792, 59714, 58964, 65609. DS sales seems to have plateaued (the slight dip probably means nothing), whereas the PSP sales got a nice spike this past week. Has everyone over there finished the new Zelda game already?

• PSP actually has more good games to play. According to metacritic, the site that aggregates major game reviews, the PSP has 53 games that are rated 80 (out of 100) or higher, whereas the DS only has 44. Although the DS has three games that score higher than any of the PSP's (Mario Kart DS, Advance Wars: Dual Strike, Legend of Zelda: Phantom Hourglass), on the whole it seems the PSP gets you better bang for your buck.

• The PSP has better PS3 integration compared with the DS and Wii. The recent upgrades to both the PS3 and PSP firmware allow for much, much better compatibility between the two than compared with the DS and the Wii. Remotely starting up your PS3 may be a neat gimmick, but they've also got remote play, which lets you access videos, music, and even games wirelessly through your PSP whether you're at home or outdoors at a Wi-Fi access point. There's been talk of using the DS as a Wii controller in many games, but the most we've seen is transferring Pokemon to your Wii or using the Wii to download DS demos—a function that the PS3/PSP also has.

• The PSP has better media capabilities. Ignoring the failed UMD movie initiative, you can still use the PSP's giant screen to play back movies off of your memory stick. There's also picture viewing, music playing, as well as remote play off your PS3, which lets you stream content from home.

• The PSP has better add-ons. Some of these are only in Japan, but the add-on camera, GPS, TV Tuner, and LocationFree TV give you four things to do with your PSP when you're not playing games.

• The PSP actually sold as well the PS2. We hate to bring up sales numbers again as proof that the PSP is picking up steam, but as J Allard famously found out, the PSP sold just as well as the PS2, hitting 10 million units within a 12-month span (give or take).

• Sony's planning a PSP Phone. Whether the PSP phone will actually support PSP games is uncertain and possibly unlikely, but the mere fact that there's a PSP phone that supports some of the PSP's functions and has some PSP connectivity will be enough to give both platforms a boost.

Does this mean that we think the DS is doomed? Certainly not. If you look at our gaming distribution between DS time and PSP time this past Thanksgiving holiday, the time spent on the DS dwarfed the time spent on the PSP about 1,000 to 1. And the DS just sold 653,000 units over Thanksgiving.

We just think this means the PSP's time has come to step out from behind the DS's shadow as the uglier, fatter, less fun cousin and show itself off as the full-featured portable media powerhouse that it really is.

Their new extended battery pack is 20% larger than the original PSP battery at 2200mAh, and comes with a special PSP replacement cover to accommodate its larger size. Running about $45 when it's released in December, the extended battery will keep PSP slims running for 10-12 hours...which is almost enough reason for us to upgrade our PSP and our battery pack.
