Quick Start

Follow the current rlab installation instructions in the source repository.

Import the ROM, then play or evaluate the immutable checkpoint:

uv run rlab import-roms ~/roms --game SuperMarioBros-Nes-v0
uv run rlab play https://huggingface.co/tsilva/NES-SuperMarioBros_Level1-4_gray84-hudcrop-stack4-simple_ppo/resolve/legacy-deterministic/model.zip
uv run rlab eval https://huggingface.co/tsilva/NES-SuperMarioBros_Level1-4_gray84-hudcrop-stack4-simple_ppo/resolve/legacy-deterministic/model.zip

Evaluation

Action selection was deterministic 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.

Release Status

This repository preserves a legacy release evaluated with deterministic action selection. It is not a schema-v1 release and has no v1 tag. A current release requires new stochastic evaluation.
