: A compressed ISO format made specifically for the PSP. While it saves space, it uses heavy compression that can cause lag and slow loading times during gameplay.
Use CHD for emulation on PC and mobile. Use ISO or uncompressed for original hardware. This means no audio degradation, no missing textures,
