What is an PVR file?
Imagination Technologies developed the PVR file extension, which stores texture files. Sega Dreamcast uses the format as a storehouse of compressed texture data optimized for PowerVR graphics system. These helped render low-level graphics in devices which had smaller screens and came with limited hardware capabilities.
Users can convert these files into other formats as per their convenience, but the PowerVR won’t support them after the conversion.
