Building a Game Boy emulator in .NET Core!
summary
Builds a working Game Boy emulator in .NET Core by transliterating the Java coffee gb codebase into C# (.NET Core 3.1), boots the Super Mario Land ROM to its title screen within hours, and reaches functional parity with the original after a day of debugging. Uses a headless mode, community test ROMs, WinForms for a simple UI, and low‑fi memory-dump diffs to sync diverging ticks; implements the 4.19 MHz 8‑bit CPU, 8 KB RAM and 160×144 display but leaves audio unimplemented for now. Explains a subtle bug fixed by restoring a regex (not string contains) and exposes the transliteration process.
