Dumb AI that tries to play classic 1987 NES Tetris

NES TETRIS AI

Running

• download Classic Tetris NES rom (I'm not sure about licensing of 30yo+ games, so I'm not including it in the repo. It's very easy to find though)
• save it as public/roms/tetris.nes
• npm i
• npm run start

Moar

• It's possible to move all the calculations to the Worker by setting WORKER to true in src/connfig.ts.
• Even it logic in the workes is the same as the one for the browser'smain thread, I just copied the code (together with configuration) because I didn't want to spend time on forcing imports to work in the Worker (or inportScripts in the browser).
• The algorithm isn't optimized for speed yet, so the non-blocking Worker version doesn't really work as expected
• To skip the loading screen on each refresh:
  • start the game
  • pause it right after the first tetramino is visible (Q)
  • run nes.save(0) in the console.
  • index.ts will load previously saved state if available
  • it's possible to have multiple starting points ("saves"), just increment the argument passed to the load/save methods
• The best result I get so far was ~517k points, what was more than enough to qualify to Classic Tetris World Championship last year. 2019 threshold was ~650k, so we're not there yet ;).
• Feel free to open pull requests with improvements.
