Is it me or do they always promise backwards compatibility and then find some cockamamie horseshit at the last minute on why it just wasn't possible. I might be a little scarred from previous promises (not specific to Nintendo).
Wii had backwards compatibility, same with Wii U. Switch couldn’t use disk so it couldn’t be. All the Gameboys had it. Super Nintendo as well. 3Ds and DS had it. Nintendo often do it.
And the GameCube compatibility of the Wii was just original GameCube hardware inside of the Wii doing all the work.
Same with PS2 hardware inside the PS3.
Having dedicated hardware inside for compatibility is not uncommon
Well, and the Gameboy is not the ancestor to the SNES so backwards compatibility is out of the window completely.
Yes, I know that the Super Gameboy is only a unfitting contender, that's why I said "kind of" in my post.
The DS even had backwards compatibility with the GBA. I think it didn't work with GB/C games though for some reason.
Someone else already pointed out that the Super Nintendo wasn't backwards compatible. The SNES' competitor was backwards compatible though -- an optional accessory for the Mega Drive/Genesis allowed you to play Master System games!
