**high-quality environments for Reinforcement Learning research and experimentation**. It provides a standard interface to popular arcade emulated video games, offering a **Python API fully compliant with OpenAI Gym/Gymnasium format**, that makes its adoption smooth and straightforward.\n\nIt **supports all major Operating Systems** (Linux, Windows and MacOS) and **can be easily installed via Python PIP**, as described in the **[installation section](#installation)** below. It is **completely free to use**, the user only needs to \u003ca href=\"https://diambra.ai/register/\" target=\"_blank\"\u003eregister on the official website\u003c/a\u003e.\n\nIn addition, it comes with a \u003ca href=\"https://docs.diambra.ai\" target=\"_blank\"\u003ecomprehensive documentation\u003c/a\u003e, and this repository provides a **collection of examples** covering main use cases of interest **that can be run in just a few steps**.\n\n#### Main Features\n\nAll environments are episodic Reinforcement Learning tasks, with discrete actions (gamepad buttons) and observations composed by screen pixels plus specific RAM states (like characters health bars or characters stage side).\n\nThey all **support both single player (1P) as well as two players (2P) mode**, making them the perfect resource to explore all the following Reinforcement Learning subfields:\n\n| \u003cimg src=\"https://raw.githubusercontent.com/diambra/arena/main/img/AIvsCOM.png\" alt=\"standardRl\" width=\"125\"/\u003e | \u003cimg src=\"https://raw.githubusercontent.com/diambra/arena/main/img/AIvsAI.png\" alt=\"competitiveMa\" width=\"125\"/\u003e | \u003cimg src=\"https://raw.githubusercontent.com/diambra/arena/main/img/AIvsHUM.png\" alt=\"competitiveHa\" width=\"125\"/\u003e | \u003cimg src=\"https://raw.githubusercontent.com/diambra/arena/main/img/SP.png\" alt=\"selfPlay\" width=\"125\"/\u003e | \u003cimg src=\"https://raw.githubusercontent.com/diambra/arena/main/img/IL.png\" alt=\"imitationLearning\" width=\"125\"/\u003e | \u003cimg src=\"https://raw.githubusercontent.com/diambra/arena/main/img/HITL.png\" alt=\"humanInTheLoop\" width=\"125\"/\u003e |\n| :-------------------------------------------------------------------------------------------------------------------: | :---------------------------------------------------------------------------------------------------------------------: | :----------------------------------------------------------------------------------------------------------------------: | :------------------------------------------------------------------------------------------------------------: | :---------------------------------------------------------------------------------------------------------------------: | :--------------------------------------------------------------------------------------------------------------------: |\n|                                                      Standard RL                                                      |                                               Competitive\u003cbr\u003eMulti-Agent                                                |                                               Competitive\u003cbr\u003e Human-Agent                                                |                                                   Self-Play                                                    |                                                   Imitation Learning                                                    |                                                   Human-in-the-Loop                                                    |\n\n#### Available Games\n\nInterfaced games have been selected among the most popular fighting retro-games. While sharing the same fundamental mechanics, they provide slightly different challenges, with specific features such as different type and number of characters, how to perform combos, health bars recharging, etc.\n\nWhenever possible, games are released with all hidden/bonus characters unlocked.\n\nAdditional details can be found in the \u003ca href=\"https://docs.diambra.ai/envs/games/\"

virtual environment to isolate your python packages installation is strongly suggested**\n\n## Quickstart \u0026 Examples\n\nDIAMBRA Arena usage follows the standard RL interaction framework: the agent sends an action to the environment, which process it and performs a transition accordingly, from the starting state to the new state, returning the observation and the reward to the agent to close the interaction loop. The figure below shows this typical interaction scheme and data flow.\n\n\u003cp align=\"center\"\u003e\n\u003cimg src=\"https://raw.githubusercontent.com/diambra/arena/main/img/basicUsage.png\" alt=\"rlScheme\" width=\"75%\"/\u003e\n\u003c/p\u003e\n\n#### Download Game ROM(s) and Check Validity\n\nCheck out available games:\n\n```\ndiambra arena list-roms\n```\n\nOutput extract:\n\n```shell\n[...]\n Title: Dead Or Alive ++ - GameId: doapp\n   Difficulty levels: Min 1 - Max 4\n   SHA256 sum: d95855c7d8596a90f0b8ca15725686567d767a9a3f93a8896b489a160e705c4e\n   Original ROM name: doapp.zip\n   Search keywords: ['DEAD OR ALIVE ++ [JAPAN]', 'dead-or-alive-japan', '80781', 'wowroms']\n   Characters list: ['Kasumi', 'Zack', 'Hayabusa', 'Bayman', 'Lei-Fang', 'Raidou', 'Gen-Fu', 'Tina', 'Bass', 'Jann-Lee', 'Ayane']\n[...]\n```\n\nSearch ROMs on the web using **Search Keywords** provided by the game list command reported above. **Pay attention, follow game-specific notes reported there, and store all ROMs in the same folder, whose absolute path will be referred in the following as** `your/roms/local/path`.\n\n**Specific game ROM files are required, check validity of the downloaded ROMs:**\n\n```\ndiambra arena check-roms your/roms/local/path/romFileName.zip\n```\n\nThe output for a valid ROM file would look like:\n\n```\nCorrect ROM file for Dead Or Alive ++, sha256 = d95855c7d8596a90f0b8ca15725686567d767a9a3f93a8896b489a160e705c4e\n```\n\n**Make sure to check out our \u003ca href=\"https://diambra.ai/terms\" target=\"_blank\"\u003eTerms of Use\u003c/a\u003e, and in particular Section 7.
