How this game was built

No human wrote this bundle. The original Breakout was reverse-engineered from a Game Boy ROM into C. Grok patches that source for every ask, GBDK compiles it back into a real .gb ROM, a bot plays the build until it passes, and the arcade watches WRAM at runtime to detect wins, losses, and your clear time.
