WonderSwan (Color)
V1 PCB
V2 PCB
With HW4/HW5 the CLK0, CLK1, EEP switches have been removed to simplify the setup. This resulted into a slight pinout change that made the WonderSwan adapter V1 PCB not compatible with HW4/5.
The WonderSwan adapter V2 PCB has a solder jumper to switch the pinout to be compatible with either HW3 or HW4/HW5.
If you have a V1 adapter and want to use it on a HW4/5 Cart Reader you can modify it by cutting the trace going to SNES pin 1 and rewiring it to SNES pin 33.
