RetroArch uzem Core: Uzebox Emulation Reference Guide

uzem is the official emulator for the Uzebox, described in the documentation as a retro-minimalist 8-bit open source game console. This guide summarizes the official libretro documentation page for the core, covering what the emulator targets, which files it accepts, and the features the documentation lists as supported or unsupported.

Background

uzem is the official emulator for the Uzebox, a retro-minimalist 8-bit open source game console. The Uzebox is a minimal system built on an AVR ATmega644 microcontroller.

The documentation credits David Etherton as an author of the core, and lists the license as GPLv3.

Files and Content

The documentation lists .uze as the supported file extension for content used with this core. It also points to a Uzebox database reference file, Uzebox.rdb, in the libretro-database repository.

Video and Audio Values

The documentation lists the core-provided FPS as 59.94 and the core-provided sample rate as 15734 Hz. The base dimensions are reported as 360 by 224, and the maximum dimensions as 720 by 448. The core-provided aspect ratio is given as 630/448, which is 1.40625.

Supported and Unsupported Features

The documentation's feature table marks States and Rewind as supported. Every other entry in that table is marked as unsupported, including Saves, Netplay, Core Options, Memory Monitoring for achievements, RetroArch Cheats, Native Cheats, Controls, Remapping, Multi-Mouse, Rumble, Sensors, Camera, Location, Subsystem, Softpatching, Disk Control, Username, Language, Crop Overscan, LEDs, and Restart.

Scope and Limitations

The documentation covers the core's background, author and license, file extension, database reference, feature table, and core-reported video and audio values. It does not include step-by-step setup instructions, usage guidance, or compatibility information, so those areas are outside the scope of this summary.
