This is a functional NES emulator developed entirely in C for the Minix 3 OS as part of a computer laboratory course. It was required building custom device drivers from the ground up, which serve as the foundation for the emulator’s hardware interactions.
Architecture #
The emulator includes essential device drivers for:
- Timer and real-time clock management
- Keyboard and mouse input handling
- Graphics rendering pipeline
- Serial port communication
Features #
- Full CPU and PPU emulation with accurate instruction execution
- Automatic cartridge detection and ROM mapping
- Support for standard NES file formats (
.neswith iNES headers) - Real controller support via wireless connection through an ESP8266 bridge
- Flexible display options with multiple resolutions and scaling
- Optimized ROM loading and unloading performance
Technical Notes #
This project was developed in a course context using a specific Minix configuration. The complete environment setup and source code are available in the repository for those interested in learning how low-level OS components interact with application software.
