Alright, I've relegated pretty much everything but the PS5, Wii U and Switch to "Museum" status. I moved all my DSi games off the New Nintendo 3DS XL, and put them on the Nintendo DSi XL, and copied all my Wii games off the Wii U back to the Wii. So they're on the original hardware they were designed for.
My original Nintendo 3DS still has all the DSi and 3DS games on it, since it's also my video card modded machine, and I can use that for streaming.
And now they're all just display pieces for now....
