Beetle Supafaust is a Nintendo SNES / SFC core for RetroArch, described in the official libretro documentation as a port of Mednafen's Supafaust SNES emulator to libretro. This page summarizes what that official documentation states about the core and its feature support, so you can tell quickly whether it matches what you need from a RetroArch SNES core.
What the core is
The official documentation frames Beetle Supafaust as a libretro port of Mednafen's Supafaust SNES emulator. It describes the core as designed to be very fast and reasonably accurate, and notes that it is fastest on ARM hardware while also expected to be speedy on typical x86 machines.
RetroArch feature support listed in the official table
The official documentation includes a feature support table for the core. Among the entries it marks as supported are saves, save states, rewind, netplay, core options, memory monitoring for achievements, RetroArch cheats and controls. Two entries are marked as not supported: Subsystem and Disk Control.
- The two unsupported entries are: Subsystem (marked as not supported) and Disk Control (marked as not supported). Both are listed this way in the official feature table, so plan around their unavailability rather than expecting them to work with this core.
