Mega Drive/Genesis + Mega CD + 32X emulator (a very widely used core).
1. Installation
- In RetroArch: Load Core → Download a Core.
- Search for PicoDrive in the list and install it.
- Return to the main menu, then Load Content to open your game.
2. Supported formats
.bin .md .gen .cue .chd
.chd is lossless compression: a single, much lighter file per game.
3. Good to know
- Settings are found under 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.
4. Not working?
- Game doesn't show up → check that its extension is among the formats listed above.
- The core won't load → update RetroArch, then reinstall it.
