Beetle PCE FAST is a libretro core for RetroArch targeting NEC PC Engine and PC Engine CD software. This page is a summary of the official core documentation; it describes what the documentation states about the core's origin and its feature-support table. It is not a hands-on setup tutorial and the steps below have not been independently tested.
Background
The official documentation describes Beetle/Mednafen PCE FAST as a libretro port of Mednafen PCE Fast with the PC Engine SuperGrafx module removed. That means the core is derived from the Mednafen PCE Fast emulator, but SuperGrafx support is not part of this port as documented.
Documented feature support
The documentation includes a feature-support table for the core. The following capabilities are listed as supported: Restart, Saves, States, Rewind, Netplay, Core Options, Memory Monitoring (achievements), Controls, and Remapping.
The same table lists a set of features as not supported by the core, including RetroArch Cheats, Native Cheats, Multi-Mouse, Rumble, Sensors, Camera, Location, Subsystem, Softpatching, Disk Control, Username, Language, Crop Overscan, and LEDs.
What the documentation implies for use
- - Save files and save states are both documented as supported, so in-game progress persistence is expected to be available through standard RetroArch mechanisms.
- - Rewind and Netplay are documented as supported.
- - Controller input and remapping are documented as supported, while Multi-Mouse, Rumble, Sensors, Camera, and Location are not.
- - Core Options are documented as supported.
- - Cheats, whether through RetroArch or native mechanisms, are documented as unsupported.
Scope and limitations
This reference is limited to what the official documentation states. It does not cover BIOS file requirements, per-game compatibility, or exact menu paths, because those details are not part of the summarized documentation claims. Any setup instructions you follow should be checked against the current official RetroArch core documentation.
