If you have extra 200 MB of space, install the FF Type-0 HD Texture Pack for PPSSPP.
FF Type-0 natively runs at 30 FPS. Activating 60 FPS via CWCheat makes animations twice as fluid.
Final Fantasy Type-0 has a known issue on PPSSPP where the characters look like they have "double vision" or a ghost trail following them. This happens when you increase the rendering resolution above 1x.
How to Fix It: This is often caused by a post-processing effect. There are two ways to handle it:
Option A: The Texture Offsetting Fix (Built-in)
Option B: The HD Texture Pack (The "Best" Way) If you want the game to look truly "better" and not just compressed, fans have created HD Texture Packs that fix the ghosting and upscale the UI.
