RetroArch 支持多个平台以及多个版本的游戏内容，覆盖雅达利（Atari）、康懋達（Commodore）、任天堂、世嘉、索尼等游戏平台，支持任天堂 NDS、Game Boy、NES、SNES 和 Virtual Boy 等各类主机，还有日电 & Hudson Soft（后者已被科乐美收购）的 NEC PC Engine 和 SNK 的 Neo Geo Pocket。
最重要的是，RetroArch 免费下载，无内购，无广告，而且开源，支持存档、使用秘籍，还可以让玩家自定义画面、快进和倒退，支持 AI 翻译以及 RetroAchievements 等功能（IT之家注：RetroAchievements 可以理解为成就奖杯和线上排名系统）。
实际上，RetroArch 很早之前就已经属于是 PC 和 Mac 平台上的知名 App，只是由于苹果的规定无法上架 App Store。
