Research direction

Start by reproducing Mortal Kombat Unchained on an iPhone 15 Pro or Apple TV with an A15 chip, using the latest RetroArch and default settings. Compare its frame rate with standalone PPSSPP and determine whether the slowdown is in RetroArch rather than the core; done means the game runs at full speed.
