This question has been asked of me a few times and I thought id make a Guide on it with images to help!
What you will need is
* Your PSP (With Custom Firmware)
* A USB Data Cable
* WinRAR Available Here (If your unsure of what OS you are running pick the 32 Bit version)
* The Game you want to play
OK! Lets Begin!
First Connect your PSP by USB to your computer and if the System does not do this by itself put it in USB Mode yourself.
* Open your PSP inside windows like so and double click to open the Rar you downloaded (In this example I'm Using Alien Trilogy). if you do not see the same icon as in my screenshot install WinRAR and check again:
* Once you have opened the RAR File you should see something like this, Now on your PSP go into the PSP Folder:
* And now into the Game Folder:
Now We want to Click and hold and Drag the folder from the WinRAR Window into the Game folder as shown in the image
* You will see a "Decompressing Window" then a Windows Will Show its moving files, This is Normal
* When it completes you should see this now to make sure the game is in there correctly enter the folder
* You should see this (sometimes there will be an extra keys.bin this is normal for some releases)
* If you see the above you have put the game correctly onto your PSP. Disconnect your PSP from your computer go to the "Game" Section in your PSP and Select "Memory Stick" In the list of games should be your PlayStation 1 game you wanted to play!
