Problems playing downloaded games(cso files)

Hello. Well i had my PSP for about 2  months. I'm still a newbie. I tried to install dev.052 and could not get it to work. I found a forum that helped step by step. I followed them and still nothing. HELP!! PLEASE!! i Followed these steps. I get stuck on step6. My PSP says my data is corrupted and PSARDumper reads the game can not be stated(8002014c).

Remove all previous devhook files from your memory stick.

2. Copy the devhook 0.52 package to the root of your memory stick. This would be ms0:/ and the three folders should be "dh", "PSP" and "fbm". If you are running OE, make sure that the DH052 folders are going into the GAME150 folder.

3. Download the 3.11 update here.

4. Get PSARDumper here. Unpack it and move the program to your GAME folder, or GAME150 if you are running OE.

5. Extract the DATA.PSAR from the 3.11 update you've downloaded with PBP Unpacker. Once thats done, copy the DATA.PSAR over to the root of your memory stick.

6. Run PSARDumper on your PSP, once its loaded up press X to dump a sigchecked 3.11. Once its done your PSP will return to the main menu.

7. Open up your memory stick, you will now see that there is an "F0" folder in the root. Move that to the "311" folder inside of "dh".

8. Finally, choose "FIRMWARE" from the devhook menu and pick 3.11. Now start devhook and you should be good to go!

i would really appreciate your help.

Re: problems playing downloaded games(cso files)

This problem occurs when there is some problem with the firmware, it can be happen If you are running official sony firmware, and/or if your firmware in custom OE/SE, you will need UMD inserted for execute devhook app. if so, i recommend you to upgrade your firmware to use the latest version of the custom firmware. 3.71 can activate the plugin for using M33 or Sony-NPL9960 driver. see here for guide. but what version is your psp?

How to downlod psp games on pc

Do you mean "How to Download Games in you PC and Play it in your PSP"?
Before you could do that, you should have your PSP installed with a Custom Firmware. S0ny hates it but its the only way you can play games that are saved in your memory card and not to keep on buying new UMD's. That's what you want right? Now, find a fellow who can configure your PSP with a CFW. Be cautious though, because installing a CFW to versions with secured board may end up your PSP useless. So that's why I said "find a fellow" if you don't really feel confident doing it by yourself.
Now, supposing you already have a CFW installed, all you need to do is to download CSO or ISO files from the internet (google the name of the Game you want to download) and download it. Hints: for a better download, use a torrent software to download these files because torrent downloader supports resume feature which enables you to download anytime you wanna do it.
After downloading your game, connect your PSP to your PC. Copy the CSO or ISO file from your PC to this directory;
where E is your PSP drive letter. Depending on your MS capacity, you can have as many games as possible.

How to install a game

There are two ways to install games on your Sony PSP (Play Station Portable).

The legit way is to buy original UMDs and insert them in your PSP and game on.

For the not-so-affluent, you can install Custom Firmware (CFW) on your PSP and thendownload games off the internet and copy them to your PSP and play them.
Play ISO / CSO Games on your PSP


1. Install Custom Firmware:

- There are scores of tutorials on the net on how to do this. The easier way out would be to go to any console shop, and get your PSP modded with CFW for around Rs. 200 / $5.

- A detailed tutorial on this coming up soon.

2. Download the Game ISO / CSO.

- Next, search for the game you want, and download the ISO / CSO of the game from torrent sites or any warez forums. Most of the times, the ISO / CSO is compressed into a RAR file so you will need to extract it first using WINRAR.

3. Copy the ISO / CSO to your PSP

- Connect the PSP to your computer using the data cable and goto Settings > USB Connection.

- Open your PSP drive in My Computer, and goto the ISO folder. If it isn't there already, create a new folder and rename it to ISO.

- Copy your ISO or CSO files to the ISO folder and disconnect your PSP from the computer.

4. Play the Game on your PSP

- Goto the GAME icon > Memory Stick and select the Game you just copied. Press 'X' and game on. icon_biggrin.gif

1. You need to have CFW (Custom Firmware) installed in order to use ISO / CSO games on your PSP. The latest version of CFW is 5.00 M33-4.
2. The latest PSP 2004 with TA 088 v3 chips and the PSP 3000 aren't moddable yet.

Which format of downloaded game will run at psp??


Thank you for using Fixya!

If you have a custom firmware (3.71 m33 or higher) then you can play game that is ISO or CSO format. You can also play games in EBOOT.PHB (PS 1 games converted to PSP).

To play ISO or CSO you need to put the file in the ISO folder in the root of your PSP's memory card. And as for the Ebot.php files you need to put that inside the root folder PSP/Game folder.

Hope this was helpful.

Iso/cso won't run to PSP version 4.20

You cannot play .iso or .cso files (or any homebrew games) on your PSP unless you have firmware 1.5 or a custom firmware. Any "off-the-shelf" firmware such as 4.2 will not support these types of files. They will just show up as "Corrupted Data".

You can go through the process of downgrading your firmware from 4.2 to 1.5, then from 1.5 you may upgrade to a custom firmware such as 5.00 m33-4. Doing so would require a good deal of technical know-how and a LOT of patience. If you do not want to risk ruining your PSP, do NOT try this. Research methods of downgrading such as "Pandora's Battery" and other firmware downgraders.

You were able to download games from the PSP website because they are programmed to play on the current firmware. Even if you were to (somehow) properly convert the .iso or .cso files to an EBOOT.PBP file, it would not run unless you have firmware 1.5 or custom.

Psp 3.95

To play ISO/CSO games on your PSP, you MUST have custom firmware installed. To install custom firmware, you need to downgrade your PSP to version 1.50/1.52. To downgrade it, you need a Pandora's Battery and a magic memory stick. You can buy the on eBay (about $10 for Pandoras battery). you can make a magic memory stick yourself easily (check videos on youtube). To make a Pandoras battery, you must be VERY carefyul because when doing this, your battery might explode because you will be soldering.(Lithium battery+Heat=Explosion). so thats what you need. If your making it urself, check the internet for tutorials(theres a lot of them)
