====== NEC PC-8800 ======

The NEC PC-8800 (a.k.a. PC-88) line is a series of computers developed by NEC between 1981 and 1989. It has a fairly long [[wp>PC-8800_series#Model_list|model list]].

The PC-8800 series sold extremely well and became one of the three major Japanese home computers of the 1980s.

This system scrapes metadata for the "pc88" group and loads the ''pc88'' 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: ''pc88.videomode'', ''pc88.ratio'', ''pc88.smooth'', ''pc88.shaders'', ''pc88.pixel_perfect'', ''pc88.decoration'', ''pc88.game_translation''

^ ES setting name ''batocera.conf_key'' ^ Description => ES option ''key_value'' ^
^ Settings that apply to all cores of this emulator ||
| **GRAPHICS API ''pc88.gfxbackend''** | Choose which graphics API library to use. Vulkan is better, when supported.\\ => OpenGL ''opengl'', Vulkan ''vulkan''. |
| **AUDIO LATENCY ''pc88.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 ''pc88.video_threaded''** | Improves performance at the cost of latency and more video stuttering.\\ => On ''true'', Off ''false''. |

=== libretro: QUASI88 ===

[[https://www.eonet.ne.jp/~showtime/quasi88/|QUASI88]] は、UNIX + X Window System ないし UNIX + SDL の環境で動作する PC-8801 エミュレータです。 (it is in Japanese, understandably)

QUASI88 is a PC-8801 emulator by Showzoh Fukunaga licensed under the BSD 3-Clause license.

This is the [[https://github.com/libretro/quasi88-libretro|libretro port]] of it.

<WRAP center round important>
It is a WIP port with the following issues:
  * No tape loading support yet.
  * Can't load BIOS files from multiple possible filenames.
  * Some keys are not mapped to the libretro keyboard.
