Building a Game Boy emulator in .NET Core!

A Game Boy emulator is implemented in cross‑platform C# on .NET Core by transliterating CoffeeGB Java code, running headless tests, then adding a WinForms UI and pixel event renderer; the Game Boy uses an 8 KB RAM, 4.19 MHz CPU and only 32 opcodes in Chip‑8 intro while the actual GB CPU has many more. Debugging uses giant tick logs and diffs to find a bad enum string check (regex vs contains), release builds fix perceived slowness, audio is not yet implemented and a quirky ASCII renderer exists.
