Arcadia 2001 / Interton VC 4000 (AmiArcadia)¶

Background¶

AmiArcadia is an emulator for Signetics 2650 CPU-based systems. It emulates the Emerson Arcadia 2001 and its many clones (Bandai, Grandstand, etc.), the Interton VC 4000 family (Voltmace, Rowtron, etc.), the Elektor TV Games Computer, and Zaccaria/Malzak coin-op arcade machines.

The core automatically identifies known ROMs by CRC32 and configures the correct machine type, memory map, and game-specific settings. For unknown ROMs, use the "Machine" core option to select between Arcadia and Interton modes.
