From 3 to 300 FPS - NES Emulation in Python and Cython

Explore the journey of optimizing a Nintendo Entertainment System (NES) emulator in Python, from a sluggish 2 frames per second to an impressive 300+ fps using Cython. Dive into the advantages and challenges of leveraging Cython to achieve real-time performance from an existing Python codebase. Learn about emulation principles, optimization techniques, and how these lessons can be applied to other performance-dependent projects. Gain insights into the viability of Python for emulator development and discover practical strategies for overcoming performance bottlenecks in your own code.
