DECO Cassette System ROM Multigame (David Widel) — About this game
David Widel’s DECO multigame gathers several games for the DECO Cassette System into a ROM-based selection. The hardware conversion replaces the normal need to install and load an individual tape with its corresponding protection module. Each selected game retains its own kind of action, so the collection has no single shared scoring goal or universal attack rule. The relevant instructions depend on which game is selected.
