Sega Genesis 3 function restore helper boards are simple little things to help when adding back the removed functions to Genesis 3 consoles.
The Sega Genesis 3 “VA1” console motherboard requires soldering wires between the cartridge port and PCB which can be difficult to do well. The “VA1” helper board adds some tracks which can be flooded with solder to connect with the pin under the cartridge port. When installed correctly it provides convenient solder pads for the function wiring to be done cleanly.
The Sega Genesis 3 VA2 console motherboard just requires two wires to complete the function restore mod. The VA2 helper board is a complete quick solder board which just makes the function restore cleaner. It also provides two convenient pads for Triple Bypass wiring.
