====== Uzebox ======

The [[http://uzebox.org/index.php|Uzebox]] is a simple yet extremely efficient and effective open source console developed by Atmel. It was released in 2008.

The physical console features a AVR ATmega644, a widely available general purpose microcontroller based on Atmel's AVR architecture. It has 4K of RAM(!), 64K of flash for both code, sound and graphics data, lots of I/O lines and many peripheral features. Read more about it [[http://uzebox.org/howitsmade.htm|at its description page]].

Batocera features libretro's Uzem, the //official// emulator.

Most software available to it has been listed on their [[http://uzebox.org/wiki/Games_and_Demos|official wiki]].

This system scrapes metadata for the "uzebox" group and loads the ''uzebox'' set from the currently selected theme, if available.

===== Emulators =====

==== RetroArch ====

[[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 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: ''uzebox.videomode'', ''uzebox.ratio'', ''uzebox.smooth'', ''uzebox.shaders'', ''uzebox.pixel_perfect'', ''uzebox.decoration'', ''uzebox.game_translation''

^ ES setting name ''batocera.conf_key'' ^ Description => ES option ''key_value'' ^
^ Settings that apply to all cores of this emulator ||
| **GRAPHICS API ''uzebox.gfxbackend''** | Choose which graphics API library to use. Vulkan is better, when supported.\\ => OpenGL ''opengl'', Vulkan ''vulkan''. |
| **AUDIO LATENCY ''uzebox.audio_latency''** | In milliseconds. Can reduce crackling/cutting out.\\ => 256 ''256'', 192 ''192'', 128 ''128'', 64 ''64'', 32 ''32'', 16 ''16'', 8 ''8''. |
| **THREADED VIDEO ''uzebox.video_threaded''** | Improves performance at the cost of latency and more video stuttering.\\ => On ''true'', Off ''false''. |

=== libretro: Uzem ===

[[https://github.com/libretro/libretro-uzem|Uzem]] is the official emulator for the Uzebox.
