It's not the same "hardware set" I'd say.

You mean like use its mapper emulation to intercept $4016/$4017 access kind of like a Game Genie? Or patch the ROM on the fly? The Everdrive does have mapper 99 listed so maybe it does something hacky with these games. I have no idea if mapper 99 was listed years ago when I tried VS SMB though.
I mean that in the same way VRC2 and mapper 150 have 1 or 3-bit wide readable registers and the rest is open bus, it's possible for a flashcart to make only the top three bits of reads from $4016 and $4017 become not open bus without inducing a bus conflict on the lower five bits
