Blazing Trails: Building the World's Fastest GameBoy Emulator in Modern C++

on YouTube ↗01h 02m

" summary

Claims a world's fastest GameBoy emulator by implementing core DMG-001 components in modern C++, measuring concrete throughput (about 50M instructions in 200 ms → 250 MBS on the presenter’s machine). Uses a webAssembly frontend and olc Pixel Game Engine for display, targets Tetris (ROM size 32,768 bytes, M-cycle precision suffices), explores tradeoffs between runtime maps and compile‑time arrays, and shows which optimizations actually lift speed versus which are just noisy anecdotes.
