What we have are schematics. Famicom schematics have been available for a while, and I don't know about SNES ones.
From schematics, though, a board must be laid out and a bill of materials drawn up. These are a considerable but not insurmountable effort. Most of this sort of work is kept private. The Analogue NT uses a new PCB design for the NES, using old Famicom parts for the PPU and CPU. Sourcing new CPUs and PPUs is the challenge. You will have to source your favorite clones, which may or may not have compatibility issues.
I was actually referring to the cart pcbs.
