For the last five years the Atari Learning Environment within OpenAI’s gym has served as the proving ground for RL algorithms. Gym Retro utilizes a more modern console than Atari, the SEGA Genesis. The Genesis has 500 times more RAM than the Atari console leading to a much greater range of possible control inputs and better graphics. The…
