The PC-FX is a fifth-generation videogame console developed by NEC. It was released exclusively in Japan on December 1994.

It adopted a desktop PC form-factor, most likely to facilitate future upgradeable hardware.

Despite being a fifth-generation console, it did not support 3D polygon graphics (probably serving as further fuel to convince Sony/Nintendo that their consoles' games should be nearly exclusively 3D, despite what the devs wanted to make). NEC's reasoning for this was that 3D processors of the time did not have high enough fidelity in their graphics compared to pre-rendered polygon graphics.

This, combined with the prohibitively high price and lack of developer support, is probably what lead to the low sales of the PC-FX. The PC-FX would mark NEC's last foray in the videogame console market.

This system scrapes metadata for the “pcfx” group and loads the pcfx set from the currently selected theme, if available.

RetroArch (formerly SSNES), is a ubiquitous frontend that can run multiple “cores”, which are essentially the emulators themselves. The most common cores use the 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] + South button (B SNES) which can be used to alter various things like RetroArch and core options, and controller mapping. Most RetroArch related settings can be altered from Batocera's EmulationStation.

Standardized features available to all libretro cores: pcfx.videomode, pcfx.ratio, pcfx.smooth, pcfx.shaders, pcfx.pixel_perfect, pcfx.decoration, pcfx.game_translation
