Show HN: A TypeScript Pokémon Crystal TUI for Agent Benchmarking

Terminal and native desktop Pokemon Crystal runtime for live play and LLM gameplay experiments.

Install once:

npm install

Start the TUI:

npm run start:tui

Start the native desktop app:

npm run start:desktop

• Move: arrow keys, WASD

, orHJKL

• A: Z

,J

, or Space - B: X

,K

• Start: Enter

• Select: Tab

• Quit the TUI: :q!

• Use Node.js 24.x

and npm10.5+

. npm run tui

andnpm run desktop

are shorter aliases.- On first run, the start command fetches the upstream pret/pokecrystal

sources and exports core runtime data only when local assets are missing. - To require preexisting local assets and skip that bootstrap, run with POKECRYSTAL_BOOTSTRAP_ASSETS=0

. - TUI audio uses PCM; ffmpeg

and MP3 audio export are not required to start the game.
