  • Can I Install Delta Emulator on my iPhone?

  • How to add Games on Delta Emulator?

Right now, there are two ways to do this:

Method 1:

  1. Open any web browser on your iPhone or iPad
  2. Open a search engine and look for the game ROM’s you want to download ( what is a ROM ) make sure it is from a reputable site
  3. Download it and, when it has been completed, find and tap the file
  4. Select Open With and choose Delta; the game will open in Delta Emulator

Method 2:

If you have Delta ROMS already stored in Dropbox, Google Drive, or any other cloud storage, you can enable syncing on your iPhone or iPad; any ROMs, cheats, saves, and save states will automatically download.

  • My ROM Won’t Import Properly, What Do I Do?

Riley Testut has produced a guide on each system, and you can check it out here. If all the guidelines are met and the ROM still won’t import, there is a good chance the ROM is corrupted. Find a new source and make sure that the ROM has been correctly zipped – it should only be the ROM, not a folder that contains it.

  • Can I Delete Games on Delta Emulator?

Yes. Find the ROM image that you want deleting and long-press on it; tap on delete and confirm on the popup window. This will not remove any ROMS that may be stored in cloud storage.

  • How Do I Transfer Files Between my Computer and iPhone?

Quite easily, but be aware that only ROMS and save states will work with another emulator.

  1. Connect your device to your computer and open iTunes
  2. Click on your device and then click Apps
  3. Click File Sharing > Delta and drag the Database folder onto your desktop – this is where all your data is
  • Will I Lose my Game Saves if I Delete Delta Emulator?

Yes. Copy all your data into the Database folder on your desktop and then reinstall the app; the data can be dragged back to it. If cloud syncing was enabled when you delete the app, any data stored in the cloud is safe and, if you reinstall Delta, you can sync it.

  • Can I install Delta Emulator on my iPad?

Yes. Delta has full support for the iPad and also for the split-screen view so you can multitask efficiently.

  • How Do I Change Skins on Delta Emulator?

Yes, you can customize and add new skins to the controllers. We have a detailed step-by-step guide to download and install Delta Emulator Skins.


The development team for Delta Emulator does not condone piracy in any way. It is illegal to download any ROM from the internet, and we urge you to buy your own games and dump ( convert from original cartridge to game ROM ) them.
