Trivia

• Charon and the System 16 version of Bloxeed have their ROMs undumped, however, it is possible to play Bloxeed officially through Sega Ages 2500: The Tetris Collection on PlayStation 2 or through MAME with one of the bootlegs listed here;
• Beauty Block and IQ Pipe are not yet emulated, meaning that there's no proper footage or proper information about the two games;
• Waku Waku Ultraman Racing is an Kids' Ride machine, not an proper Arcade game;
• Fantasy Zone II DX: The Tears of Opa-Opa is an re-imagination of the Sega Master System game of the same name, despite the original game being ported to Sega System E hardware one year later.
