The console itself is in good condition, has all the cords. It is yellowed in the front.
I've got Final Fantasy III, Link to the Past, Super Mario RPG and Super Mario World . All are cartridge only, and all but Final Fantasy III have dust covers on them. the labels are all intact, and in good condition. There are price stickers on the backs of each cartridge, usually on the back sticker.
There's also a sticker on the system itself, but that shouldn't be hard to take off.
EDIT: I've also got a 2nd controller for the system.
I've also got a loose Game Genie for the SNES,
The console and games have been in a clear plastic storage box in my closet. My home is smoke free.
