Yes, and what i've figured out is this..

When i download ISO files i get 2 things, A floder labeled 'PSP_Game' and another file called 'UMD_DATA.BIN'

And i can't run these ISO files.

Itried putting both files in the ISO folder and i even tried putting the 'PSP_Game' folder in the ISO folder while i placed the 'UMD_DATA.BIN' in the x:/PSP/Game folder.

But when i download a CSO file it runs just fine on my PSP.

So i just need to know how to figure out these ISO files, thanks!

im too lazy to look at all the replys but try getting a 512mb stick and make a magic one outta that. thats what i did. plus i hardmodded my battery so it could also be that the battery u bought was faulty. or maybe ur psp is just retarded. basically a "retarded psp" means that something is wrong with the motherboard in the psp and is preventing u from doing anything to the psp. the only option is to buy an new one. make sure its a fat psp. the slims need special software installed to make it work.....hope this helps.

Well, hack4life.

I acctually found out that the only problem i was having was that i have Windows Vista,

I used my friends Windows XP and it worked just fine but thanks anyways!!

Now i'm just trying to figure out how to play ISO files on my PSP using the 'PSP_GAME' and 'UMD_DATA.BIN'

you'v gone to far on winrar go back a step so you have an .iso file and extract that

winrar can open iso folders so when ever you hit the PSP_GAME folder just go back a step
