Beetle PCE

Mednafen core for RetroArch. It covers the following systems: PCECD, PCEngine, PCEngineCD.

1. Installation

1. In RetroArch: Load Core → Download a Core.
2. Search for Beetle PCE in the list and install it.
3. Return to the main menu, then Load Content to open your game.

2. System files

This emulator relies on files taken from the original machine. Extract them from hardware you actually own.

Files expected according to our listing:

• syscard3.pce

Indicated location: bios/

BIOS for PC Engine CD

3. Supported formats

.pce .sgx .cue .ccd .chd

.chd is lossless compression: a single file per game, noticeably smaller.

4. Good to know

• Settings are found under Quick Menu → Options, once the game is loaded.
• Remember to Save Core Overrides/Options to keep them from one session to the next.
• Controllers are configured once, under Settings → Input, and apply to all cores.
• A setting that works well for one system won't necessarily suit another: adjust on a case-by-case basis.

5. Not working?

• Refuses to start or black screen → a system file is missing, misnamed, or not in the expected location.
• File rejected → its checksum doesn't match the expected one; the dump is probably incomplete or comes from a different model.
• The game doesn't show up → check that its file extension is among the formats listed above.
• The core won't load → update RetroArch, then reinstall it.
