PyGB
A GameBoy emulator written in Python
Current Progress
- Memory Space, mapped out, with tests for special echo space
- Load and describe a rom
- A fair number of instructions implemented
- A bare bones graphics tick to get code waiting for VBlank etc working
Current Stage
- Finishing all of the CPU instruction implementations
- Setting up proper instruction timings
- Ensuring the graphics timings are correct
- CPU instruction tests passing
Reasons for creating this project
- To learn how to write a hardware emulator
- Gain a powerful perspective about how things were done in the past
- I appreciate this piece of hardware a lot, and played the hell out of it as a kid
- General Python Practice
Requirements
- Python 3.5+
How to Run
- Clone this repository
- Run python3 main.py --rom "Path to the rom you want to run"
