Caltron Industries Inc. was a Taiwan-based video game company that produced one unlicensed cartridge for the Nintendo Entertainment System.

This cartridge is a 6 in 1 multicart which includes six seemingly original Caltron productions, although their true origins are still largely unknown and many are clones of existing titles - some of these games have appeared both before and since, with various alterations, on pirate Famicom and NES cartridges.

The six games on the cart are:

• Bookyman - A clone of Williams and Kural's arcade game Make Trax/Crush Roller, which had previously been released by Hwang Shinwei /RCM - Shinwei's version featured graphics taken directly from the original, while they were modified in the Caltron release, presumably to avoid legal trouble.
• Adam and Eve - A single-screen platform game similar to Nintendo's Balloon Fight, in which you have to kill snakes by bursting the balloons attached to their heads.
• Cosmos Cop - A pseudo-3D into-the-screen shoot-em-up, similar to Sega's Space Harrier in a futuristic setting.
• Magic Carpet 1001 - A horizontally-scrolling shoot-em-up, later released on pirate cartridges as "Aladdin 3" and with some graphical and sound modifications as "Super Harry Potter".
• Balloon Monster - A clone of Mitchell's Pang , or Buster Bros. as it was known in North America
• Porter - A puzzle game similar to Sokoban (originally by Thinking Rabbit ), in which you have to move boxes into a specific place.
