If you really want to play Gran Turismo or Castlevania on the go, Sony's PlayStation Portable is a great way to do it. But it gets harder and harder to justify carrying around a PSP handheld gaming console when you've got an equally powerful Android phone in your pocket already. The PSP had a good 10 years before being discontinued, and your Android can pick up the slack now.
So, what I'm saying so far is that you can play psp games on your android phone.
So to do that, you'll need what is called a psp emulator, which is an android app.
I'll recommend using psspp app, I've been using it for years.
1. Now, after the app has been installed open it
2. Click on Games
3. Then choose the folder where you've downloaded your psp iso file into
4. Then click open the game by clicking on it
And as you can see from the screenshot below the psp game is opened on an android phone.
That's all on how to play psp games on your android phone
I'll be posting articles on psp game files you can download, so do well to follow me.
