I forgot where I got it but I have a perfect fit and shape male solder type plug for my genesis and plan on using the wire loom from this pcb kit to work with the same pcb and go over to vga with it.

I would like to use that pcb and grab one of H's bartops and have the best of all words for the console's.
I have.
original xbox with the official hd av pack
psone on the redant vga box
ps2 on component or redant vga box but would not power through ps2 mem card port so I modded it to use a 7.5v wall plug

dreamcast with vga cable from
www.aliexpress.comwii with official component cables
gamecube with official component cables
genesis self made cable using the hardware mentioned above pretty much that plugs into the stock console port and then goes to the harness that plugs right into the 5-pin port on the pcb in the link like it was made to be.
snes would like to do the same but looking for the hardware to make it happen.
I think it would be pretty cool to be able to swap them out of the bartop like that while having the best of display's for each still

crafty's SLG is in the future for the gens ps1 and snes too.
still looking into the original xbox vga bios to see what that is all about and if it is better then component or not.
