How to put Psp Iso in the memory stick

I know this question have been asked but I think some things weren't answered. So please just tell me. After I download the games what do I do? Extract them with winrar then put them in which folder. And I see that the games come in various parts. What to do with them? Just put all the parts in the same folder? If so, will the game run just fine? Or is there another step you have to do first?

 

You have to extract them into the same folder. I.E: PSP Isos

Then you have to combine them. WinRAR will combine them just by double clicking on them.

The end result is the ISO itself.

 

Yes. Just extract the RAR file. Afterwards, plug in your PSP to your PC.
Bring up the drive that your PSP is in. make a folder in your root drive named ISO , i.e. MS:\ISO\
Then Drag the game (.iso, .cso, .jso, .dax) into the ISO folder you have just created.
If the files are not in iso or cso formwhen you download it, the file is extractable with WinRAR.

Hope that made sense
