It is quite common to face performance issues, but you can easily gain a performance boost by tweaking some system and graphics settings. Note: the performance of the games depend on the hardware specifications of your phone. Your touch gestures will not work while playing the game, only the on-screen buttons will. While the game is playing you will see on-screen buttons similar to the ones seen on the original PSP. Tap on the game you want to play and it should launch.
By default, PPSSPP shows a phone’s internal storage in the “Games” section, but you can tap the “Upward Arrow” at the start to move back to the area where your SD Card (extSDCard) folder is located (see screenshot below). Tip: I once had a really bad time trying to play games from the SD card, as I couldn’t find the location where the SD card option was located (took me approximately 3 hours!).
