The full story
The Nubo author describes a Rust Game Boy and Game Boy Color emulator made largely with Claude Code under human direction. Their submission adds the emulator and its launch options to the Game Boy Emulator Shootout harness.
The author reports 261 passing tests out of 264 on Windows, with the remaining three lacking reference images rather than failing. That is the contributor's local result, not an independently repeated benchmark.
