I cant play the game in memory stick..


you'd first have to downgrade your psp. try to lower it to 3.50 or 4. something. then insert the .pbp file... this file is a hack.. or an upgrader for a psp.. once you do this.. your psp will be back to version 5.03 but now you can play downloadable games.

I upgrade my psp in version 5.01, now i cant play my games


HELLO! There's no need to downgrade ur PSP. If u have upgraded ur PSP from the official site and a official firmware has been installed on to ur PSP, it won't execute games(ISO,CSO) from ur memory stick. It will only run games from the UMD. If u want to run ur games from a memory stick u have to install a CUSTOM FIRMWARE. Try www.psp-hacks.com these guys have many softwares on their site. Dont worry its not that hard to put a Custom firmware onto ur PSP.

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.

I cant play games from memory


Hi kalfan

What happened was that when you downgraded your PSP to -play game from your memory stick, that version was loaded onto your PSP for a reason. What you did now is install the latest firmware and that disabled you from playing games from your memory stick. You might have to get your PSP downgraded again with the older firmware version.

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)
