"All Nintendo published games had the Nintendo sleeve. All third party licensed games had a plain black sleeve. It's possible some other companies may have used Nintendo sleeves as well but we need more info on this." Yes, third-party companies did use Nintendo sleeves. I have a collection of NES games of which I am the original owner. In the picture, the 3rd party games that stick out of the line (6 in total) all have Nintendo sleeves (the games in the picture that are NOT sticking out all have either a Nintendo sleeve (Nintendo published), or a blank sleeve (3rd party published).). Since my brother and I always kept our games in the boxes, there wasn't much opportunity to mix sleeves up. Never brought our games to friends' houses, either, or vice versa. P.S. Not pictured but also 3rd party games with Nintendo sleeves: T&C Surf, and Teenage Mutant Ninja Turtles.
