How to play winrar games on PSP

Hello everyone, I got a new PSP and went from 2.6->2.8>1.5>3.10OE-A in order to play homebews. I learned today how to play ISO on my psp. However I am trying to now learn how to play a game on my psp that I had previously converted to winrar using a dumper software. So basically my question is: how do I go about to take a winrar game that is on my pc back to my psp and play with it. The winrar does not have iso or cso but it contains folders and many other files

Thanks

You cannot run games compressed with winrar. You'll need to extract the file and then rebuild the files into an iso or cso.

use UMDGen for this, grab it from the downloads section.

thanks again x3shpere, I will try it out and will post a reply on how it all went.

Do the rar files have extensions like .rar .r00 .r01 etc. ?

no, when I open the winrar it has a psp game folder and other folders. It is the same way as you would get if you coverted a UMD game into a winrar using a dumper software. I will try x3shphere' solution it seems like it answers my problem
