Japan version and worldwide version of Bloxeed use different boards.
Japan version is running on System 18 hardware (released in 1989). It was developed as the succeeding model of System 16 (1986) on which Tetris and other notable games were developed. System 18 added some custom chips to improve the expression, and it adhered to the JAMMA standard unlike previous systems by Sega.
The worldwide version of Bloxeed was developed on System C (1989), hardware with a similar architecture to the Mega Drive console with a cheaper production cost. Columns and Columns II were developed on System C too, but this was also used by Atlus's "Print Club" photo booth, or used for the monitors of kiddy rides and popcorn vending machines.
SEGA AGES Tetris Collection, a PlayStation 2 port of Bloxeed implements the System 16 version as same as on Tetris, as the special appendix.
Japan version (System 18) and Worldwide version (System C) have the following differences:

Dip switches of System 18 version work as written in the following table (a JPG file). Bold letters mean the factory settings (everything is set to OFF). The number 1-4 switches of SW1 correspond to the first coin chute. The number 5-8 switches of SW1 correspond to the second coin chute. The English explanation of SW2 is available from the Arcade Restoration Workshop website.
