# 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.

The right analog stick maps to keypad keys 1-9 (excluding 5) in 8 directions, matching the layout of the original keypad:

```
7 8 9 ↖ ↑ ↗
4 6 = ← →
1 2 3 ↙ ↓ ↘
```

Console buttons (Start, A, B, Reset) are only active on Player 1.

## Keyboard

Desktop keyboard input is supported for Player 1's keypad. Both the number row and numeric keypad are mapped.

| RetroKeyboard Inputs | AmiArcadia Inputs |
|------------------------------|-------------------|
| Keyboard 0 / Numpad 0 | Keypad 0 |
| Keyboard 1 / Numpad 1 | Keypad 1 |
| Keyboard 2 / Numpad 2 | Keypad 2 |
| Keyboard 3 / Numpad 3 | Keypad 3 |
| Keyboard 4 / Numpad 4 | Keypad 4 |
| Keyboard 5 / Numpad 5 | Keypad 5 |
| Keyboard 6 / Numpad 6 | Keypad 6 |
| Keyboard 7 / Numpad 7 | Keypad 7 |
| Keyboard 8 / Numpad 8 | Keypad 8 |
| Keyboard 9 / Numpad 9 | Keypad 9 |
| Keyboard [ / * / Numpad * | Keypad Clear |
| Keyboard ] / # / Numpad Enter | Keypad Enter |
