getting the downloaded games from the pc to the psp

I have finally uploaded, downloaded to 3.40 oea. I have managed to put Sonic onto the memory card and the game works fine. However i am now having trouble getting fifastreet from the pc onto the psp. I have done it the same way as sonic but its not working. When i double click the saved game on the pc it shows a psp folder an iso folder a dh folder and an instruction folder. Do i put all these folders into the iso on the psp or do i seperate them.

If anyone can explain to me exactly how to transfer the games to psp that would be great or if there is a link to an idiots guide that would be good to.

Is it not the same way for all downloaded games?

Please help

you just need to take the iso or cso file from the iso folder and place it in your iso folder on your psp... dh stands for dev hook which is a reallllly prehistoric application that used to load games.

thanks guys its working now.
