Many people think Sony psp games are overpriced, so here's a tutorial about downloading free homebrew psp games from the web to your computer and installing them on your psp.
Commercial Psp games are contained in small discs that you can easily carry around, however you may also store them in your memory sticks.
Get a Memory Stick for your PSP:
The PSP comes with a small 32MB card that isn't big enough to store a lot of video clips and games, so you need to purchase a larger memory stick. These cards come in different sizes, if you have enough cash get a 1gb memory stick, but consider that 256mb should be enough. Then, insert your new memory stick into your PSP and reformat it.
Download the games to your computer:
You will be downloading the so called “Homebrew PSP games" to your psp; they are custom design games produced by programmers. They emulate other gaming consoles and let you play games from consoles such as Nintendo, Supernintendo, Megadrive, Neogeo and much more. Homebrew psp games are downloadable all over the web and are usually compressed into zip file archives. Please be sure that the files you download end with “psp", this is because the programmer has ported the game to different consoles and platforms, and only a version with “psp" in the filename will be compatible with your PSP.
Unfortunately, most homebrew PSP games work with Firmware 1.5 and under only (Sony is trying to block people from playing homebrew psp games), so check out your psp firmware version and if you do have a later version of PSP, please think about downgrading you PSP. If you have a firmware later than 1.5 you may often get errors such as “The data is corrupted" or “The game could not be started".
Connect the PSP to your computer:
Ok, you have just downloaded the games to your computer, now just put your PSP into USB mode and connect it to the PC via a USB cable; the operating system will identify your PSP as a removable memory, assigning a drive to it. Drag and drop your PSp games into this drive, in the PSP>GAME directory. If the “PSP" and “GAME" folders don't already exist on your PSP's Memory Stick, then you need to create two new folders (name them in ALL CAPS).
Disconnect the PSP from your computer:
After the PSP games are completely transferred to your memory stick, disconnect the USB cable connecting your PC to the PSP.
Play the downloaded games:
Once you have finished copying the games onto your memory stick, select the GAME column on your PSP and then the memory stick option; you should be able to see a list of available games.
Errors? If you find any error on your PSP (such as “corrupted data error"), chances are you downloaded a game that is not compatible with the version of firwmare installed on your psp.
