Скачать или смотреть Game Gear HDMI Adapter, initial testing

Very early prototype using my GBA HDMI board to get a 1280x720p output from the Game Gear.

The custom PCB uses a Spartan6 FPGA to convert the Game Gear's 160x144 12-bit RGB video into a 1280x720p HDMI output using a 4x integer scale. HDMI video is generated directly from the FPGA, audio is taken from the Game Gear's headphone jack.

It has some pixel glitches, but it could be due to the wiring as it's very sensitive to positioning. The Game Gear was bought as a "broken" unit and is in need of a cap replacement, that could also be causing issues.

Next steps are
-add in 5x integer scaling so that the Game Gear can fill the screen vertically.
-replace 5v to 3.3v resistor voltage divider pcb with a proper
5v to 3.3v level shifter circuit.
-synchronize the GG and FPGA board to get rid of screen tearing.
-solder in controller wires so that a SNES controller can be used.
