Polygonet Commanders was a failed 1993 arcade game by Konami, running on an arcade board intended to go head-to-head with the Sega Model 1 board in terms of flat-shaded 3D graphics. Only two games were ever released on this hardware, the second being Poly-Net Warriors.
Under the hood, the system sported a Motorola 68EC020 as the main CPU, a Motorola DSP56156 for processing 3D geometry, a quartet of custom chips for filling the horizontal spans of the geometry, a Konami PSAC custom for rotate/zoom ("Mode 7"-style) graphics, a simple 8x8 tilemap implemented in discrete logic, and a Zilog Z80, Konami custom K054321, and Konami custom K054539 to handle sound.
Cabinets could be linked together for local networked play.
The two games have remained without 3D graphics in MAME for over a decade, primarily due to the DSP56156 core having a myriad of bugs.
While it still clearly has its share of bugs, this is the first time that it's been able to run its geometrizer program successfully enough to produce any data at all, let alone recognizable polygon data.
