The DECO Cassette System was an early-80s Data East arcade platform that loaded its games from cassette tapes inserted into the motherboard, an uncommon solution that let operators swap titles without replacing all the hardware. This "Multigame" is an unofficial compilation gathering several of those titles on a single board, something common in the market for replacement boards and homebrew collections.
Its interest is mostly technical and historical: a curiosity for anyone wanting to explore Data East's early catalog and that particular hardware solution the company abandoned just a few years later.
