About this component
Flipper does far more than graphics: it holds the GPU with its TEV texture combiner, 3 MB of embedded 1T-SRAM (2 MB framebuffer/Z-buffer and 1 MB texture cache), a Macronix-designed audio DSP, the main memory controller and the I/O for the disc drive, controllers and memory cards. Because so much routes through it, a Flipper fault can show as no video, no disc read or no controller response. It is a large BGA under the heatsink and is not practical to replace.
What it does on this board
162MHz GPU also handling audio and I/O; 3MB embedded framebuffer.
