Smallest snes mobo

[Nortier]

Im am currently working on my snesp and I got my case and hipgear screen sorted but I am wondering which has a smaller mobo the fc 16 go or the retroduo? I assume the fc 16 go is smaller but is it even possible to use it without the other mobo in the fc 16 go?

fc16go is smaller, and yes you can use it standalone.
