Welcome to GTA5FORPSP.COM, We are the official creator of the GTA 5 on PSP. As you know it has not been officially released on PSP, we managed to patch it from the version of the PS3. So, the controller settings might be slightly difficult to use. PS3 controller has more buttons so we had gone through different procedure to make it better. We are updating the game as per the requirements of the customer so, If you have any suggestions then contact us at: email@example.com.
