A libretro core for emulating Signetics 2650 CPU-based systems, based on DroidArcadia by James Jacobs.

• Emerson Arcadia 2001 - and compatible systems (Bandai, Grandstand, etc.)
• Interton VC 4000 - and compatible systems (Voltmace, Rowtron, etc.)
• Elektor TV Games Computer

• Zaccaria - Astro Wars, Galaxia, Laser Battle, Lazarian
• Malzak - Malzak I & II

# Build for current platform
make

# Build with debug symbols
make DEBUG=1

# Clean build artifacts
make clean

The compiled core will be named amiarcadia_libretro.dylib (macOS), amiarcadia_libretro.so (Linux), or amiarcadia_libretro.dll (Windows).

• Save States - Full save/load state support using the COS format
• RetroAchievements - Memory exposed for achievement tracking
• Core Options - Machine selection, region (PAL/NTSC), sprite demultiplexing
• Two Player Support - Full two-player input with analog paddle support
• Keyboard Input - Desktop keyboard support for keypad overlay

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.

Supported ROM extensions: .bin, .tvc

Tests use the libretro.py library and require Python 3.11 or 3.12.

# Setup (one-time)
cd test
python -m venv venv
source venv/bin/activate
pip install libretro.py pytest

# Run all tests
./run_tests.sh

# Run specific test file
pytest -v test_smoke.py

ROMs should be placed in an Emerson - Arcadia 2001/ directory accessible to the tests.
