Description
Hey HN! Wanted to share a fun project I've been hacking on. Given Jev can make decisions really fast (but not fast enough to play Doom yet sadly), I wanted to try and push it to play a more complex game than Tetris. So I went with Pokémon.I've spent endless hours playing this game as a child so building this was a ton of fun.I open sourced everything in case you want to hack on it yourself here: https://github.com/christianmat/jev-pokemonThe game is being streamed live including the tokens and cost - hopefully we get all the badges and don't get stuck in a cave :)

Could you build this?
Partial Streaming an emulator to a web page is straightforward, but engineering an AI agent capable of fast, cohesive decision-making over long-horizon RPG game states requires specialized RL or agent-architecture design.
What it would actually take: The stack uses a Game Boy emulator core (like PyBoy) wrapped in Python, interacting with an agent via memory-mapped state observation (reading RAM addresses for coordinates, battle states, and menu selections). The hard part is the decision policy: designing a low-latency hierarchical agent with spatial memory, pathfinding heuristics, and contextual state caching rather than relying on naive frame-by-frame VLM prompting.
Discussion
20 comments analyzed.
Competitors mentioned: OpenAI
Concerns raised: Excessive harness guidance and railroady choices, Model acts mostly as an RNG without state memory, Single-shot classifier ill-suited for multi-step RL tasks, Lack of intelligence compared to leading LLMs
Feature requests: Feed previous decisions back into context state, Integrate with a vLLM to view reasoning logs, Test on models with Pokemon training data abliterated

Nobody's really built a agent / copilot tool for Agriculture yet.
