PAC-MAN Reimagined (C++ / SDL2)

A native C++20 + SDL2 Pac-Man — co-op multiplayer, procedural chiptune audio, and a full CMake build that targets both desktop and an ARM aarch64 retro handheld (EmuELEC). ~3,000 lines of modern C++, built with sanitizer / coverage / strict-warning presets and an automated test suite. Not a tutorial port — a from-scratch game with its own architecture.

Highlights

• Modern C++20 + SDL2, no game engine — hand-written game loop, rendering, input, and audio.
• Co-op multiplayer — two Pac-Men plus the four classic ghost AIs (chase / scatter / frightened).
• Procedural chiptune — a software audio mixer synthesizes sound in code (no audio asset files).
• Cross-platform build — desktop (native) and ARM aarch64 (Amlogic S905X2 handheld via EmuELEC); CMake toolchain files for cross-compilation, plus device packaging scripts.
• Engineering rigor — separate CMake build presets for AddressSanitizer, coverage, strict warnings, and native/ARM targets; automated tests under tests/.

Build & run (desktop)

cmake -S . -B build-native
cmake --build build-native
./build-native/pacman          # adjust to the actual target/exe name

Tests

ctest --test-dir build-native

Layout

• src/, include/ — game source (loop, rendering, ghost AI, audio mixer, game state)
• tests/ — automated test suite
• cmake/, packaging/, scripts/ — cross-compile toolchain + device deploy
• assets/ — game data
• CMakeLists.txt — build configuration (multiple presets)

Why it's here

Modern C++ game built from scratch — game loop, enemy AI, collision, a procedural audio mixer — cross-compiled to real ARM hardware, with sanitizer/coverage/strict build modes and tests. A clean demonstration of systems-level engineering.
