ASO: Armored Scrum Object was officially released on September 3, 1986, by SNK Electronics. But before it was released, and as is true of almost all games, sample carts were provided to various people, likely including journalists writing game reviews. The cartridge in the picture below is one of the many ASO sample cartridges given out before the game's official release. Often times, sample cartridges have different gameplay, graphics, options and music than the official release.

A cheaply printed label for this sample cart.

No back label.

In the case of this sample cartridge, the cart was sometimes accompanied by an audio cassette tape. It's a bit odd since the game includes the music and sound of the official release. What's on audio tapes that accompanies these is unclear.

All of the ASO sample cartridges had the number of the sample cartridge stamped onto a label and placed on the cartridge, possibly to track who got which cartridge. In the case of this cartridge, it's #00285. Out of how many total cartridges is unknown; lower numbers have been seen for sale on Yahoo! Japan Auctions.

#00285.
