Ningún juego de PS4 puede ser convertido mágicamente a un emulador de PSP. Si ves un tutorial que muestra a FighterZ corriendo en PPSSPP, es un video editado o una estafa.

Once you have located the files on the Internet Archive, follow these steps to set up the game: Install the Emulator : Download and install the PPSSPP app from the Play Store or the official site. Organize Game Files : Place the downloaded file in a dedicated "Games" folder on your Android device. Apply Textures Extract the "Textures" folder from your download. Move this folder to PSP/TEXTURES/
