How to import .iso files in PSP?

[Krezey]

I wanted to install Tekken 6 in my PSP, I looked in google for a .cso file of Tekken 6 except the only thing that kept showing up are .iso files. I know that .iso files are better than .cso, but I don't know how to use a .iso file.

I tried installing the .iso file and people kept saying "Just extract the .iso in your ISO folder" I looked at the .rar file and checked what's inside. The only thing there was PSP_GAME and DATA. I looked at PSP_GAME there was loads of files, it didn't had an .iso file, the DATA file was a video so I ignored that.

My friend said you need a USB connector, here's another question, can I use the SD Card instead of the USB connector? What's the difference?

So tell me how to import an .iso file to play it on my PSP. Thank you.

From what I know:
~You have to have a custom firmware.
~You need a PSP USB Cable.
~You need a memory card of course.
~The game you want to import.

To import:
~Plug-in your PSP to PC using the USB Cable.
~Assuming this is PSP1000, Slim and Lite, 2000, 3000, go to system settings and hit USB Mode.
~Now go to you computer and find your PSP.
~Open it, inside there should be a folder called "ISO"
~Extract the game which I assume should be a .rar or .zip file when downloaded. Extract using WinRAR.
~The file inside that .rar or .zip file is the actual .iso game itself.
~Just copy that .iso file inside the "ISO" folder and you're done.
