HD-64 is an RF-modulator replacement for the Commodore-64 computer which features a Full-HD 50/60Hz Micro-HDMI video+audio output. Crucially, the HD-64 is not a replacement for the VIC-II, which still needs to be mounted on the motherboard
Instead of digitizing the VIC's analog video output signal, the HD-64 "sniffs" the C64's memory bus and recreates a pixel-perfect video output by means of emulation implemented on FPGA. The reconstructed video is then upscaled to Full-HD resolution, merged with the digitized audio from the SID, and sent out as HDMI.
