OpenEmu
Every retro console behind a single library window that looks like it came from Apple.
What it does
OpenEmu wraps established emulator cores — Nestopia, Snes9x, Genesis Plus GX, Mupen64Plus, Mednafen and around thirty others — in one native Cocoa application. Drop a ROM in and it identifies the system, fetches box art and metadata, and files it in a library that behaves like Music did.
Save states, rewind, shaders, controller mapping per system and screenshots are handled once, at the front end, rather than differently in every emulator.
Notes
- Nintendo DS, Saturn, PSP and newer systems live in the separate Experimental core set, enabled in preferences.
- Because the cores are third-party, accuracy and compatibility are whatever that core does — OpenEmu’s contribution is the shell around them.
- Emulation is lawful; obtaining the games and any required BIOS files is only lawful from hardware and media you own. Nothing ships with either.
Alternative to
| Alternative | Type | Trade-off |
|---|---|---|
| RetroArch | Open source | The same idea with vastly more cores and a worse interface |
| A standalone emulator per system | Open source | Better accuracy and per-system options, no library |
| Dolphin | Open source | GameCube and Wii specifically, far ahead of any core |
| Nintendo Switch Online | Subscription | The licensed way to play a much shorter list |
