Phosphor Emulator

Phosphor is a free retro game emulator for iPhone, iPad, Mac, and Apple Watch. Play Game Boy, Game Boy Color, and Game Boy Advance games, plus Nintendo DS games on iPhone and iPad, with save states, fast-forward, rewind, iCloud save sync, controller support, and community mods.

No ads. No subscriptions. No accounts. No tracking.

Import your own compatible ROM files through Files, iCloud Drive, or AirDrop. Organize your library, pick your controls, and take your favorite handheld games anywhere.

WHY PHOSPHOR?

Phosphor is designed to feel like a handheld console. Deep black screen wells, glowing CRT effects, responsive controls, and color themes bring classic games to modern Apple hardware. Play in portrait or landscape, adjust your speed with a scrolling dial, and return quickly to your last session.

NINTENDO DS ON IPHONE AND IPAD

Import compatible .nds files and choose single-screen or dual-screen play. Start with a focused single-screen layout, switch to both screens from the menu, and swap screens when you need to. Touch-screen input, microphone controls, and portrait and landscape layouts keep DS play flexible.

MODS POWERED BY GEN1RECOMP

Supported games can use the integrated gen1recomp engine to run compatible community mods inside Phosphor. Keep your library, controls, and display framing while exploring new ways to play.

The updated engine brings gameplay and compatibility fixes. Features vary by game, engine, and mod. Rewind and cheat codes are available with Phosphor’s standard emulator core, not during gen1recomp play.

BRING YOUR OWN GAMES

Phosphor does not include games or ROMs. Provide your own legally obtained, compatible game files.

Community mods have their own authors, licenses, and compatibility requirements. Save states and other features may vary between emulator cores, engine versions, and devices.

A classic handheld feel. Modern Apple features. Your games, your library, your way to play.
