 The current emulation of the Atari 800 based family of computers is not complete or fail safe. This wiki article only gives basic instructions so you can run some popular games. The full technical background on these issues can be found in this article: [[https://www.raphkoster.com/about-raph/hobbies/emulation/atari-8-bit-guide-for-lr-atari800-and-retropie/|Atari 8-Bit Guide (Raph Koster)]]. The script mentioned in these pages is **not** integrated into Batocera yet, so you are stuck with the manual fixes until then. The current emulation of the Atari 800 based family of computers is not complete or fail safe.

 There are subtle differences in machine type between the different Atari Computers, including different version of the OS (BIOS).

-[[https://docs.libretro.com/|RetroArch]] (formerly SSNES), is a ubiquitous frontend that can run multiple "cores", which are essentially the emulators themselves. The most common cores use the [[https://www.libretro.com/|libretro]] API, so that's why cores run in RetroArch in Batocera are referred to as "libretro: (core name)". RetroArch aims to unify the feature set of all libretro cores and offer a universal, familiar interface independent of platform. +RetroArch has [[emulators:retroarch|its own page]].

-=== RetroArch configuration === +
- +
-RetroArch offers a **Quick Menu** accessed by pressing ''[HOTKEY]'' + {{:wiki:south.png?nolink&20|South button (B SNES)}} which can be used to alter various things like [[:advanced_retroarch_settings|RetroArch and core options]], and [[:remapping_controls_per_emulator|controller mapping]]. Most RetroArch related settings can be altered from Batocera's EmulationStation. +

-Standardized features available to all libretro cores: ''atari800.videomode'', ''atari800.ratio'', ''atari800.smooth'', ''atari800.shaders'', ''atari800.pixel_perfect'', ''atari800.decoration'', ''atari800.game_translation'' +
