Should these carts be added to the SNES database? Most of them are not even mentioned in the descriptions. I mean these only because they are verifiable and were produced with the intention of being a demo. The ones with the stickers are not verifiable and not produced with intention. Any cart couuld be a demo when you slap one of those stickers on there.

01 Starfox
02 Stunt race FX
03 Donkey kong country
04 Donkey kong country 3
05 Turtles in time
06 Killer Instinct
07 Tetris attack
08 Yoshis Island
09 Contra
10 Mortal Kombat II
11 Ken Griffey jnr
12 NCAA basket ball
13 Street fighter II
14 Street fighter II Turbo

This list was taken from a thread that I started where PredatorXS stated his entire collection of demos for the SNES. He included pics, so they do exist.
