NeoCD

RetroArch (libretro) core for Neo Geo CD (NeoCD). It covers the machine: NeoGeoCD.

1. Installation

1. In RetroArch: Load Core → Download a Core.
2. Look for NeoCD 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 hardware. Extract them from hardware you own.

Files expected according to our sheet:

• neocd.bin

Indicated location: /bios/

Neo Geo CD BIOS required (neocd.bin, 524 KB). neo-geo.rom may also be required depending on the core.

3. Supported formats

.cue .bin .chd .iso

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

4. Good to know

• Settings are found in Quick Menu → Options, once the game is loaded.
• Remember to Save Core Overrides to keep them from one session to the next.
• Controllers are configured once in Settings → Input, for all cores.

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.
