I have a PSPGo and I, after putting on a bunch of PSP games from EmuParadise, decided I want to play PS1 games on here since I heard it was possible. Is it the same process I use for PSP games( I'll tell process at the bottom to avoid confusion)? 1.Download the ISO from emuparadise.com. The standard ways to play games on the PSP are by using a UMD or through the Sony PlayStation store. However, with PSP ISOs, these present another way to play such emulator games with its included advantages of faster game speed and less memory use. The Sony PlayStation Portable or PSP was a handheld game and multimedia entertainment console. These are the only ways to play games from your memory stick on your PSP, including PS1 ones. Don't listen to the guy below me. Because I downgraded then installed custom firmware on my PSP, and I can play the latest UMD games. He only has a small clue about what he's talking about but probably has no idea what custom firmware can allow you.

Game > Playing games downloaded from PlayStation®Store > Copying games to play on a PSP™ system

If the game that you have downloaded (as a purchase or for free) from (PlayStation®Store) is compatible with the PSP™ system, you can copy the game to play it on a PSP™ system.

Connect the PSP™ system to the PS3™ system using a USB cable.
To copy files to Memory Stick™ media, insert the Memory Stick™ media into the PSP™ system.

On the PS3™ system, select the game that you want to copy under (Game), and then press the button.

Games that can be played on either PS3™ or PSP™ systems

If you are playing a game that is compatible with both systems, you can copy saved data from the game from one system to the other so that you can continue playing where you left off. The method for copying saved data varies depending on the game type.
