Gamecube, N64,3DS, Virtual Boy(lol) and Wii U. I think it beats the Gameboy and GBA but that's mostly from my inexperience of those two platforms. The next console for the Switch to beat is probably the SNES or NES.
I own
GBA
GC
DS
Wii
3DS
Wii U
I have tons of virtual console games and both NES and SNES classic minis. So I am very well versed in what the systems I do not have.
