AmiArcadia is an emulator for Signetics 2650 CPU-based systems." --- # 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. ### Author/License The AmiArcadia core has been authored by - James Jacobs The AmiArcadia core is licensed under - Non-commercial A summary of the licenses behind RetroArch and its cores can be found [here](../development/licenses.md). ## Extensions Content that can be loaded by the AmiArcadia core have the following file extensions: - .bin - .tvc ## Databases RetroArch database(s) that are associated with the AmiArcadia core: - [Elektor - TV Games Computer](https://github.com/libretro/libretro-database/blob/master/rdb/Elektor%20-%20TV%20Games%20Computer.rdb) - [Emerson - Arcadia 2001](https://github.com/libretro/libretro-database/blob/master/rdb/Emerson%20-%20Arcadia%202001.rdb) - [Interton - VC 4000](https://github.com/libretro/libretro-database/blob/master/rdb/Interton%20-%20VC%204000.rdb) ## BIOS The AmiArcadia core does not require any BIOS files. ## Features Frontend-level settings or features that the AmiArcadia core respects. | Feature | Supported | |-------------------|:---------:| | Restart | ✔ | | Screenshots | ✔ | | Saves | ✕ | | States | ✔ | | Rewind | ✔ | | Netplay | ✕ | | Core Options | ✔ | | [Memory Monitoring (achievements)](../guides/memorymonitoring.md) | ✔ | | RetroArch Cheats | ✕ | | Native Cheats | ✕ | | Controls | ✔ | | Remapping | ✔ | | Multi-Mouse | ✕ | | Rumble | ✕ | | Sensors | ✕ | | Camera | ✕ | | Location | ✕ | | Subsystem | ✕ | | [Softpatching](../guides/softpatching.md) | ✕ | | Disk Control | ✕ | | Username | ✕ | | Language | ✕ | | Crop Overscan | ✕ | | LEDs | ✕ | ### Directories The AmiArcadia core's library name is 'AmiArcadia' ### Geometry and timing - The AmiArcadia core's core provided FPS is 60 for NTSC and 50 for PAL - The AmiArcadia core's core provided sample rate is 11025 Hz - The AmiArcadia core's base width is 164 (home consoles) or 240 (coin-ops) - The AmiArcadia core's base height is 226 (NTSC) / 269 (PAL) for home consoles, or 240 for coin-ops - The AmiArcadia core's max width is 240 - The AmiArcadia core's max height is 269 ## Core options The AmiArcadia core has the following option(s) that can be tweaked from the core options menu.
