It exists because Sega's original intention for the SC-3000 computer was to allow other manufacturers to produce compatible computers in the hope of having a worldwide standard. Unfortunately, possibly with the emergence of the MSX, this tactic failed, and very few SG-1000/SC-3000 compatible machines were produced. The Othello Multivision was one of these machines. This system scrapes metadata for the "multivision" group and loads the ''multivision'' set from the currently selected theme, if available. {{ https://raw.githubusercontent.com/fabricecaruso/es-theme-carbon/master/art/consoles/multivision.png?nolink&350 |}} ==== Quick reference ==== * **Emulator:** [[#retroarch|RetroArch]] * **Core:** [[#libretro:_genesisplusgx|libretro: GenesisPlusGX]] * **Folder:** ''/userdata/roms/multivision'' * **Accepted ROM formats:** ''.bin'', ''.sg'', ''.zip'', ''.7z'' ===== BIOS ===== No Multivision emulator in Batocera needs a BIOS file to run. ===== ROMs ===== Place your Multivision ROMs in ''/userdata/roms/multivision''. ===== 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: ''sg1000.videomode'', ''sg1000.ratio'', ''sg1000.smooth'', ''sg1000.shaders'', ''sg1000.pixel_perfect'', ''sg1000.decoration'', ''sg1000.game_translation'' ^ ES setting name ''batocera.conf_key'' ^ Description => ES option ''key_value'' ^ ^ Settings that apply to all cores of this emulator || | **GRAPHICS BACKEND ''sg1000.gfxbackend''** | Choose your graphics rendering\\ => OpenGL ''opengl'', Vulkan ''vulkan''. | | **AUDIO LATENCY ''sg1000.audio_latency''** | Audio latency in milliseconds, turn it up if you hear crackles\\ => 256 ''256'', 192 ''192'', 128 ''128'', 64 ''64'', 32 ''32'', 16 ''16'', 8 ''8''. | | **THREADED VIDEO ''sg1000.video_threaded''** | Improves performance at the cost of latency and more video stuttering.
