You can start playing retro games in 15-20 minutes. No technical skills needed. Whether you want Super Mario Bros., Pokémon Red, or Zelda games, Delta makes it simple. Your device stays secure and your warranty remains valid.

What You Need Before Starting

You need these items to install Delta directly:

  • iPhone with iOS 14.0 or newer (iOS 16+ works best)
  • Apple ID account that works properly
  • Good internet connection (Wi-Fi is better for downloads)
  • At least 500MB of free space on your phone

Important: Back up your device first. Delta install is safe, but backups are smart.

Step 1: Open the Official App Store

Find the blue App Store icon on your home screen. Tap it to open. You will see the main screen with tabs at the bottom. These tabs say Today, Games, Apps, Arcade, and Search.

Step 2: Search for Delta Emulator

Tap “Search” in the bottom-right corner. Type “Delta” in the search bar at the top. Tap the search button. Look for “Delta” by Riley Testut. It has a red and blue logo. The description should say “Game Emulator.”

What happens: Delta appears as the first or second result. It has a red and blue geometric logo and many good ratings.

Step 3: Install Delta from the App Store

Tap the Delta app to open its page. You see screenshots, reviews, and details about the app. Tap the blue “GET” button to start the direct install process. Use Face ID, Touch ID, or your Apple ID password when asked.

The install takes 2-3 minutes. You see a progress circle fill up as Delta downloads.

What happens: The “GET” button changes to “Installing” with a progress bar. Then it says “OPEN” when done.

Step 4: Launch Delta and Set It Up

When install finishes, tap “OPEN” from the App Store. Or find the Delta icon on your home screen. The first time you open Delta, you see a welcome screen. Tap “Continue” to go through setup.

Delta asks for file access permissions. Tap “Allow” so Delta can use your Files app. This lets you add games to Delta.

What happens: Delta opens to show your game library. You see tabs for different consoles (GBA, GBC, NES, SNES, N64). No games show yet.

Delta is just the emulator software. It does not include games. You need ROM files (digital game copies) through legal ways:

  • Make backup copies of games you own
  • Use ROM dumping tools to copy your cartridges
  • Download free homebrew games

Legal note: Downloading copyrighted ROM files without owning the real game is illegal in most places.

What happens: You understand how to get games legally and are ready to add ROM files to Delta.

Step 6: Add Your First Game ROM

To add a game, you need a ROM file in your iPhone’s Files app. When you have a legal ROM file, tap the “+” button in Delta’s top-right corner. Choose “Files” from the menu. Find where your ROM file is stored.

Tap your ROM file to bring it into Delta. Delta detects the console type automatically. The game goes to the right section. Game Boy Advance ROMs go in the GBA tab.

What happens: Your game appears in the right console tab with cover art. It is ready to play.

Step 7: Set Up Controls and Options

Before playing, tap the gear icon in the top-left corner. This opens Delta’s settings. You can change:

  • Control layouts for each console
  • Save state locations
  • Fast-forward speeds
  • Audio and video options
  • Controller support for external controllers

For touch controls, tap “Controller Skin” then pick your console type. You can resize and move the on-screen buttons.

What happens: Controls work the way you want. Games feel good on your iPhone screen.

Step 8: Start Playing and Use Save States

Tap any game in your library to start it. Delta shows the game with controls on the bottom of your screen. To save progress, tap the menu button while playing. Choose “Save State.” This makes an instant save you can return to anytime.

You can make multiple save states per game. This lets you try different strategies or go back to specific moments.

What happens: Your game runs smoothly with good touch controls. Save states work perfectly.

Fixing Common Problems

Delta does not show in App Store search: Make sure you search in the right region’s App Store. Try searching for “Riley Testut” instead.

Install fails or app will not open: Restart your iPhone and check storage space. If problems continue, delete the app and install again.

ROM files will not import: Check that ROM files use supported formats (.gba, .gbc, .gb, .nes, .smc, .sfc, .n64, .z64). Extract compressed files first.

Games run slowly or have audio issues: Close other apps and turn off Low Power Mode. Check Delta’s performance settings.

Controller will not connect: Make sure your controller is charged and paired in Settings > Bluetooth before opening Delta.

Save states do not work: Check that Delta can access Files in Settings > Privacy & Security > Files and Folders.

External Controller Support: Connect MFi controllers, Xbox controllers, or PlayStation controllers for better gaming.
