游戏 Magic Jewelry

Magic Jewelry is a NES unlicensed tile-matching puzzle video game derivative to Columns, which was programmed in Taiwan by Hwang Shinwei and published by RCM Group in 1990, without a license from Nintendo.

This title is common on pirate Famicom multicarts and systems; for example, it's built into the Dynavision and Power Player Super Joy III but existed also two hacked versions, called respectively Abacus and Coin Tetris (the first only on N-Joypad).
