Which System Libraries Do You Have Access To?

[Signalstar]

What console/handheld platform libraries can you play using the hardware that you currently own? Obviously not taking piracy or illegal emulation into account. Based on the consoles you own and their backwards compatibility, what games can you play.

I own PS5, PS4, PS3, PS Vita, Switch, 3DS, and Wii.

Through PS5 I can play - PS5 + PS4 games.

Through PS4 I can play - PS4 games.

Through PS3 (Original Fat 60GB) I can play - PS3, most PS2, and PS1 games.

Through PS Vita I can play - Vita games, PSP digital games.

Through Switch I can play - Switch games.

Through 3DS I can play - 3DS + DS games.

Through Wii I can play - Wii + Gamecube games.

So even though I own 7 pieces of gaming hardware, I can access the libraries of 12 different platforms thanks to BC. I do play across libraries pretty regularly actually.

What about you?

Here's an interesting thought experiment, what's the minimum amount of hardware you would need to own to be able to access the libraries of all mainstream gaming platforms?
