In a similar way to Action 52, this multicart features six different games made by Mega Soft, although most of these are rip offs of other games. Many have criticised this multicart for its games being of poor quality, although it's often cited as being better than Action 52. Both versions of this are known for being extremely rare.
- Cosmos Cop (Space Harrier clone)
- Magic Carpet 1001 (generic shoot-em-up)
- Balloon Monster (Pang clone)
- Adam And Eve (Balloon Fight clone)
- Porter (Sokoban clone)
- Bookyman (Brush Roller hack by Hwang Shinwei, which was based off Make Trax)
Myriad 6 in 1Edit
When Caltron Industries, Inc. was going out of business, a company based in Kingwood, Texas called Myriad Games, Inc. bought all of their existing cartridge inventory. Myriad then took the carts and added a very generic (no graphic art) label. They were then packaged in custom boxes with a folded manual. Each Myriad cart and box were numbered individually.
Myriad's only change to Caltron's product was to replace the label with their own. In fact, you can see the edges of the Caltron label visible at the edges, as the Myriad label is slightly too small to cover it. No programming changes were done, hence the game is exactly the same. To this point, the title screen still reads "Caltron". The six games on the cart are identical to Caltron's release.
Shortly after the release of 6-in-1, Myriad went out of business for unknown reasons. The game has become one of the rarest unlicensed games made for the NES. Collectors speculate that fewer than 100 copies exist, and even fewer are complete. The most valuable copies are those with box, instructions, and cartridge with matching serial numbers. The lowest known serial number is 000032 and the highest is 000888. At least two sealed versions are known to exist.
- All six games would later be released on the Asder 20-in-1.
- The title screen of Adam & Eve shown on the back of the box is completely different to the released version.
