Weird square button famicom CPU

[famiac]

I have an odd square button famicom cpu which appears to have a different PPU and there is also a rubber insulator under the PPU rather than a metal heatsink above it... its really weird/cool. I can take pictures if anyone wants.

Ok. It has an rp0c02d ppu. Ill take a picture when i get home. I didnt do much research but all the square button cpu's have a metal heatsink.
