"It's running with what was essentially a Commodore 64 accelerator in the guise of the "SuperCPU". Released in 1996 and based around the 65802 MPU, it plugged into the cartridge slot acting as a pass through and ran at 20MHz - the architecture also allowed for the increased memory storage required to run Doom. They're incredibly hard to come by now, but thankfully can be emulated. Links are in the description."
