Downloaded PSP Games

I was wondering if its possible to play downloaded psp games with any firmware.. or do you have to have a custom one...
oh and yeah im sorry im not on alot i do come every few days to check any news and stuff..

u need custom firmware to play "downloaded games" but there called ISO's

ah wow that was fast lol, thanks oh well i may have a custom one after a long time of having my psp fixed.. when i get it fixed..

How do you play these downloaded games? Is there a tutorial on it? Ie what files are needed, where to put them etc?
Presume this is playing games from memory cards?

There called ISO's because of the file format there in, which is iso. All you do is search a website that hosts torrents and download a torrent that contains a psp game. The only file needed is the iso (some are compressed, which are called cso and are smaller with less files in the cso) and you put them in a folder titled ISO on the root of your memory stick. Its simple as that.

And before you ask, your not allowed to post links to websites that contain torrent's because its pirated software and illegal. But if you ask, someone can pm you links.
O and all the iso is, is a ripped copy of an official psp game taken off the umd and put into a file. They can be rather big sometimes (500mb compressed) but some are as small as 60mb compressed.

My PSP is running normal firmware at the minute, about 2.81 i think. What do i do? Do i downgrade and get custom firmware? Where are these available from? Are there quides for this?

update to 3.03 and get the original GTA LCS and the downgrader here

sorry, why get original GTA LCS???

Because it has an exploit in it that allows you to downgrade to 1.50.
