Can I download psp games for free using a 3.03 version?

I know where! Go to http://pspgames.campolar.net.tc and then to and then see the Sony PSP Games list and download many games. More games are added every day. I guarantee most of these games work if u have an OE Custom Firmware with an “ISO” folder in it, or an ISO and CSO emulator like devhook. If you have a firmware newer than 3.40 then you can update it to 3.52M33. To download them go to: http://pspgames.campolar.net.tc and read the NOTE at the top and have loads of FUN! This website is legal because it has shared games. Meaning these are games which other people uploaded on file sharing websites and allow other to share it. It’s just like a friend giving you a game!

No, not exactly. To play LEGAL BACKUPS of your UMD discs you would need to hack your PSP's firmware, to a custom programmed or "homebrew" firmware. This is accomplished through a process known as downgrading - and it does pose some risks - which include bricking your PSP. Not to mention completely voiding your warranty. Seeing as how sharing and downloading UMD backups is illegal, I can not advise you as to where or how you can download them. Best of luck.
