HOW TO HACK YOUR SLIM PSP FOR HOMBREW APPLICATIONS
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
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).
