It is latest Modchip for 3206 drive. No need to cut any wires from the drive board. It is fully support fdsstick read/write disk.

I confirm 3206 modchip is not compatible with fdsstick read/write.
When it is develop, fdsstick haven’t appear. So, I can’t know that.
It is working good except fdsstick. Like Copy Master 1.1, Disk Hacker else.
Also, it can work with any fds game with save function like Zelda.

I’m finding a way to make it compatible with fdsstick. But need some times.
I will check what different with Copy Master and fdsstick read/write.
Hope will fix soon. Sorry.

If you use Modchip, it is easier to install.

You need to mod both Power Board and Drive Board.

Drive PCB mod :
1) Modchip pins don’t touch anything from PCB.
2) Drive PCB need to cut two wires and solder 8 wires to the Modchip.

Power Board v05 Mod :
Cut two wires and solder two wires.
