We've moved! We decided to concentrate all ALE-related resources on its GitHub repository.
In case you want to download ALE's latest releases, raise an issue, or collaborate in the project, visit us at:
If you have any questions or comments about the ALE, please contact us through our mailing list.
There are multiple other extensions/wrappers of the ALE. Two of the most famous ones are DeepMind's xitari and OpenAI's Gym.
