Megaswitch HD
News

On my Genesis 1 VA2, I developed all the released firmware for two years. And only today I replaced the blue (test) boards on it with purple ones.

Master System mode. Board-C release. Megaswitch HD Update v1.27.0  
March 23, 2025

Release of Board-C and new firmware v1.27.0 for Megaswitch HD.

Sega Master System mode (on Genesis\MD console) is now output via HDMI, due to the additional Board-C board.
March 17, 2025

Over the last week I have continued developing a new firmware for HDMI rendering of Sega Master System games. Board-C has met all expectations.
March 16, 2025

I received the chips and soldered the Board-C prototype. But now I’m soldering pre-orders of Board-A and Audio-ADC. As soon as I finish, I can return to developing the Master System firmware for the Genesis HDMI mod. 
February 26, 2025

Received the Board-C prototype test board.
It will help continue the development of Master System firmware for the HDMI Genesis mod.
But I need to wait 2-3 weeks for the chip for this board. 
February 09, 2025

I'm working on the ability to display Sega Master System games on an HDMI mod for Genesis\Mega Drive.
And I'm glad to share the news.
Showing games in the future will be possible.
The main FPGA will recreate the SMS VDP and the Board-C will connect the Z80 data.
