Building a Gameboy Emulator
summary
Walks through a line-for-line transliteration of CoffeeGB into C# on .NET Core, showing how headless mode boots real ROMs, how opcodes map to a switch-driven CPU loop, and how pixels are emitted as an integer-packed framebuffer then drawn via WinForms bitmap display. Describes building test harnesses and a memory-hash sync to find the exact CPU tick where two emulators diverge, fixes a regexp-vs-Contains bug in MBC enum handling, and ships an ASCII-art CLI renderer.
