Import the ROM, then play or evaluate the immutable checkpoint:
1uv run rlab import-roms ~/roms --game SuperMarioBros-Nes-v0
2uv run rlab play https://huggingface.co/tsilva/Level2-1_stable-baselines3-ppo_4792f358/resolve/v1/model.zip
3uv run rlab eval https://huggingface.co/tsilva/Level2-1_stable-baselines3-ppo_4792f358/resolve/v1/model.zip
Evaluation
Action selection was stochastic under the published evaluation environment contract.

Limitations
Evaluation establishes performance only for the published environment hash, start distribution,
policy preprocessing, and action-selection protocol. It does not establish generalization to
other levels, environments, ROM revisions, or contracts.
Licensing
The rlab-authored policy weights and publication material are licensed under the MIT License in
LICENSE. Emulator/runtime software and game assets remain governed by their own licenses and
terms. This repository does not redistribute a game ROM.
Policy Lineage
This is a legacy rlab policy trained by Stable-Baselines3 PPO. It is not a GradLab-trained checkpoint and no GradLab compatibility is claimed.
