Learning Low-Level Computing and C++ by Making a Game Boy Emulator - The Making of GameByte
Summary
This blog post chronicles Michael Webb's journey to build a cross-platform Game Boy emulator in C++. It covers the motivations for learning low-level computing, the CPU/MMU structure, opcode handling (including CB prefixes), and the PPU, along with practical progress like achieving playable Tetris, using test ROMs, and implementing MBC1 for cartridge banking. The piece highlights challenges and learning moments, and notes missing features such as sound and full accuracy.
