About

Delta is an all-in-one video game emulator for non-jailbroken iOS devices. With Delta you can relive the experience of playing several iconic Nintendo consoles, including SNES, Nintendo 64, Nintendo DS and more! Delta is the spiritual successor to GBA4iOS — a Game Boy Advance emulator I made while in high school — rebuilt from the ground up with modern iOS features and support for more systems.

Save States

Save and load save states for any game from the pause menu.

Automatically makes backup save states to ensure you never lose your progress.
Support for “Quick Saves,” save states that can be quickly saved/loaded with a single button press (requires external controller).

Fast Forwarding

Speed through slower parts of games by running the game much faster than normal.
Easily enable or disable from the pause menu, or optionally with a mapped button on an external controller.

Hold Button

Choose buttons for Delta to hold down on your behalf, freeing up your thumbs to press other buttons instead.
Perfect for games that typically require one button be held down constantly (ex: run button in Mario games, or the A button in Mario Kart).

3D/Haptic Touch

Use 3D or Haptic Touch to “peek” at games, save states, and cheat codes.
App icon shortcuts allow quick access to your most recently played games, or optionally customize the shortcuts to always include certain games.
