Currently, this program will only run on PSPs with firmware version 1.0 or 1.50. If you do not know which firmware version your PSP has, or if you need help installing this application/game on your PSP, check one of our many informative FAQs. If you have a higher firmware version than 1.50 on your PSP, you cannot run this program. Check out our previous coverage on how to downgrade [here].
Thanks for the translation help neko. =)

Ok so you?ve decided to downgrade to PSP firmware v1.50, now what? Unlike firmware versions 1.51 and up, both firmware version 1.00 and 1.50 allow the running of unsigned code (homebrew) on it. Sounds great, but what does that mean for you?

As I?m sure you?ve seen on this site, there are many ?homebrew? games, emulators and applications that can allow your PSP to do a multitude of things that otherwise would not be possible. There are emulators (program which are made to emulate say a Super Nintendo), games written solely for the PSP, and applications such as PDF viewers and MP3 players.

?Awesome! How do I do it?? We get this question in our email several times daily and I hope this will clarify most all of the questions you have, however there are things that I will most likely miss and can be easily found by using the Search button in our forums.

Let?s start with the basics of installation. To install a program on your PSP you will need a USB cable which will go from your computer to your PSP. Below is an example of what I use (with a built in charger.)


Simply plug in the USB cables to your Computer and PSP, then on your PSP?s menu move all the way to the Left (Settings) and up one to ?USB Connection.? Once your USB cables are plugged in, press the X button on USB connection and you will be inside of your Memory Stick drive.

Ok, now that you?re inside the Memory Stick and ready to copy files, what now? All programs you will download will need a file called ?Eboot.PBP? (think executable file for the PSP) to be able to launch the program. Many times you will download a file with only one Eboot.PBP in the archive, however PSP firmware 1.50 requires that you have 2 ?split? Eboots to launch successfully. This is because 1.00 firmware only required to have one Eboot, and when 1.50 was cracked it required two Eboots (that were split from a 1.00 Eboot.) Other times you will find that inside an archive there will be only two directories titled something like ?/GAMEZ? and ?/GAMEZ%? (inside /PSP/GAME). That is how the 1.50 Eboot file setup will look once on your memory stick. If you download a program like this, simple copy both folders to ms0:/PSP/GAME. There are some programs out there that will do the install for you just by having your PSP in USB mode and clicking install on the Eboot. A couple examples are:

Sei?s PSP Tool v0.5c ? Download [here]. Or
Stefano Russello?s PSP Brew v0.53 ? Download [here].
QPSPManager v1.2.1 by Bernat Rafales Mulet for Linux - Download [here].

Now that you have the tools for converting 1.00 Eboots to 1.50 and installing, what else is out there? Quite simply, a lot. There are a multitude of emulators for the PSP ranging from Atari to Super Nintendo (Even a ScummVM emulator for playing Monkey Island.) Some of the many emulators for the PSP are:

Along with emulators, there are many homemade games for the PSP that authors have graciously spent hours of time coding for the better of the community, such as:

Squarez v0.8.1 by Globware ? Download [here].
Polygon (Bejeweled clone) by The Grey Matter ? Download [here].
Attack of the Mutants v0.2 by DeNitro ? Download [here].

PSPAdvance v1.5 Beta by Andy Fung - Download [here].
SmashGPSP v0.2b by mATkEUpON - Download [here].
And TONS More which can be found in our PSP Games Download section [here].

There are many more games than what I have just listed, and there are also games created in a scripting language called Lua which was ported to the PSP by Shine and Nevyn. With Lua, you will need a program called Luaplayer (current version 0.11 ? Download [here].) With Lua, you must have the Lua player Eboots inside a directory and can either use a program called Lowser (included with Luaplayer), or just use standalone Eboots for each program (uses more space.) To install, move the whole program folder into /PSP/GAME/luaplayer/Applications/. Alternatively you can rename ?index.lua? to ?script.lua? for a standalone Lua program to be run (with the Luaplayer eboots in the same folder inside of /PSP/GAME) Some Lua programs include:

PSPQuarium by puffo83 ? Download [here].
PSP Duck Hunt by Yashamaru ? Download [here].
Laserix by Bigmoor ? Download [here].
Minesweeper v1.2 by JEK - Download [here].
Jezzball by JEK - Download [here].
Many more Lua games can be found in our PSP Download section [here].

Additionaly, there are many more programs for 1.50 that will help you keep that firmware, and customize it the way you like. A long time ago there was a program called PSPersonalize by vampire and DrEggman which allowed you to change your background images. There have been programs to swap the X and O buttons and even fake your firmware version so UMD games think you are running version 2.0 when you really aren't. You can also change a file called gameboot.pmf to show a different movie clip instead of the white PSP screen when loading something. These programs will write to the PSP?s flash memory and as with any programs that do so, you must use caution as they could brick (permanently damage) your PSP. Programs that can help you do this are:

WAB Version Changer v2.5 ? Download [here].
PSPSet v0.9 by Placasoft ? Download [here].

I know this does not cover all the programs (sorry everyone I did not mention) and abilities that the PSP can (and will) perform, but I hope this gives everyone a good start on running homebrew on the PSP.

Sakahi has ported Neko Project 2 to the PSP. Neko Project II is a PC-9801E emulator. The PC-9801E belongs to the non IBM compatible NEC PC-98xx family. This console was available in Japan in 1983 for the low price of 215,000 yen. This emulator is simply beautiful as far as emulators go. It has a windows 3.1?like feel with many menu?s, mouse support and a virtual keyboard. Even if you have nothing to run with it I?d suggest checking it out, it?s a preview of what homebrew will become.
