Hi,

these are the steps you will use to download a game on your psp.
step 1
Your regular PSP games will come on disc, or UMD as they are known. When you download games onto PSP however, you are going to be putting them straight onto a memory stick/card. (Some people call them memory sticks, and some people say memory cards, but they are in fact the same thing.) The standard PSP memory card of 32mb is just not going to be big enough to download games onto, PSP owners should generally get the largest one they can afford. These days you can find fairly affordable 2 or 4 gig models on Ebay and Amazon quite easily. Once you have your new memory card, you will need to format it before use. This is basically like wiping the slate clean before use, so be sure to do it.


step 2

You will need to locate somewhere to download the games from. There are hundreds of places online that will allow you to download games onto PSP, but unfortunately they are not all reliable-if you go to the wrong places you will encounter many problems and can even find your computer riddled with spyware after. Not good! Be sure to choose a reputable site to download PSP games from-the most reliable ones are the ones that charge a small fee upfront and then give you access to unlimited downloads.


step 3

Once you begin downloading to your computer, be sure to only download files that end in "PSP" or have "PSP" in the title, as they are the only files compatible. You will occasionally find that the untrustworthy sites out there will try and give all kinds of files as downloads, so be sure to double check everything before you download it. When downloading the games I save them to a little folder on my desktop called "PSP Downloads, as it's simply the easiest place!


step 4

Now that you have a selection of games downloaded, you will need to transfer them from your PC onto the memory card of your PSP. This is pretty simple, all you will need is an ordinary USB cable to connect the two, and the PC should then identify the PSP as some form of removable drive, like a flashdrive or removable HD. All you need to do from here is to open up the PSP using the PC and drag and drop the required files onto the PSP memory stick, much as you would with any other removable drive. When you are doing this, be sure to send the files into folders called PSP, and then GAME on your memory card. If they don't exist you will need to create them, and I would recommend using all caps.


step 5

Once the transfer is finished you should be able to play the games on the PSP by simply opening up the GAME menu and selecting the games from the stick. Any errors or error messages are likely to be due to incompatible firmware-this is especially true if downloading homebrew games. You may find it necessary to downgrade your PSP in order to play these homebrew games.

Hopefully this guide has helped you see that it's not that tough at all to download games onto PSP once you get the hang of it, the real trick is finding a reliable download source!

Please rate my solution.

Hi,

For you to download and play games on your psp, please follow the steps listed herein;

1. Since you can download directly to your PSP memory stick, you'll have to download to your computer and further transfer to your PSP memory stick.

2. You'll have to modify the PSP from the official version to a custom version. You can find out how to do this by typing in this search "How to hack PSP to custom firmware"

You can now do the following to transfer and play games;


a. Get a good memory stick. I recommend that you get a Memory Stick Duo in at least a 1 GB size, though a 2 GB is even better.

b. Find and download the PSP games you want. If you don't know where to find the games try a download service. A good one will let you have unlimited downloads for a small one-time fee. You can see the link below for more information.

c. Unzip the game files and save them somewhere that you can find them easily, like your desktop.

d. Plug your PSP USB cable into your PSP and your computer.

e. For PSP games- go the the root directory on your PSP then make a folder called ISO. (If you downloaded PSOne games, go to the root directory on your PSP and find the folder called PSP/GAME.)

f. Copy the PSP game files into the ISO folder. (Copy PSOne game files into the PSP/GAME folder.)

Once this is done you can now play games on your PSP.

if you are sure that you put the save file in the right location try another save file and see if that loads up. if it does then the save file you want might be corrupted. u can try downloading it again and see if that helps

There are different kinds of games for the PSP. There are Flash games, ISO/CSO games, PBP Games, etc. Depending on your firmware type, (Custom or Official) there are special kinds you can play:

Flash games are small, quick games you can play on your PSP Browser. They don't require special firmware to run. However, the flash games tend to run slow because of the lack of memory. Download them to your PSP/COMMON Folder and type in the location of the content in the address bar. 

Ex: file:/psp/common/name.swf

For PBP Games, you can download them from the PSN and save them to your PSP/GAME Folder. These games are mostly demos. The PBP Files should have its own folder under PSP/GAME. To play them, go to your game section of your XMB and if you did it correctly, the game should be there. 

Now, for ISO/CSO files. These are Disc image files that can be played on your PSP. They're usually for backup purposes. You save them in your ISO Folder (You might have to make this folder). To play them, just play as you would with a PBP Game.

it depends on your version of psp try upgrading to 5.03GEN-A

Custom firmware (needed to run pirated/ISO/CSO games) can't be run for the PSP 3000 series. You may download demo games from the Play Station Network and they are all playable. You can play MP3s and WMA files (needs activation) on them though. Put your music files on your MS inside the MUSIC folder (create the folder if there is none present).

you got to put the downloaded cso file format into a folder in the psp called iso
or jus check out on youtube

have you been downloading games,if you buy new games they should save fine,if not take them back and refund, if you downloaded games then the must have some corrupted data on them when downloading causing save issues. deleta data and try downloading from more trusted site like pspiso, or just google em
