I cant download FREE psp games to my PSP!!!!!!!!!!!!!!!!


i'm sorry this might sound as a bad news to you but if you are running on an official firmware, the only free games you would get are demos which you can download from the playstation network via your psp apart from that, there are no methods of getting free psp games that would run fine on official firmwares.
although there is an alternative of downgrading your psp to a custom firmware which would allow you to play homebrew games or allow you to download psp games onto your memory stick and play them.
it is important for you to note that downgrading your psp is not safe and it also requires quite an amount of expertise. it is advised you give it to an expert if you are to opt for this option.

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.

Downgrade psp firmware 5.02


Someone will have to run the flash program to get you back to M33. Pandora battery and Magic stick with M33 flash on it. Most homebrew and programs will not run on any M33 version above 3.9. New UMD games from sony will have the latest firmware and the children will usually run the firmware upgrade to play the game. It will allow the new UMD to play, but the Sony Firmware will write over the Custom M33 firmware and you will not be able to run the games on your Memory stick.

Cannot play copied games in psp's memory stick after updating


Hi Aneeshameeda

I think the best solution is to downgrade your PSP system software to the original version and check if your games load. What might have happened is that the firmware software that was on the PSP was downgraded to play copied games, and now you've changed the firmware to a newer version and that is why your games won't load. You might hac=ve to get your PSP downgraded again to play the games from your memory card.

Downgrade PSP from 3.80


It's impossible to downgrade your PSP from it's current version. I'm not quite sure why you'd want to downgrade, but maybe you should upgrade (If a version is available) again and see if you like that version better. ^-^
