So, you’ve got your GAEMBABY Case. You’ve felt the satisfying click of the buttons and the nostalgic texture in your hand. You’ve nailed the Physical Experience.

Now, it’s time to give your iPhone its Digital Soul.

To transform your iPhone into the ultimate handheld, you need to understand two key components: Emulators and ROMs. Here is everything you need to know to get started.

1. The Emulator: Your Virtual Console

Emulators serve as digital players for retro games, recreating the experience of classic consoles on your iPhone. Currently, Delta is the most popular and user-friendly option available on the App Store.

2. The ROM: Your Digital Game Cartridge

If the emulator is the "Console," then the ROM is the "Game Cartridge"—the digital file containing all the game's data.

Finding Your Favorites

Building a digital library is a straightforward process. Most players find their favorite classics by searching for terms like "GBA ROMs," "GBC ROMs," or "NES ROMs" online. Once a file is downloaded, it typically saves directly to the Files app on your iPhone, where it can be imported into your emulator with a few taps.

3. Why Physical Buttons are the Final Piece

You might wonder: "Can’t I just play on the touchscreen?"

Technically, yes. But for any retro enthusiast, glass just isn't the same. It lacks the tactile soul of the original experience. When you snap on the GEMEBABY Case, something magical happens. The physical feedback aligns perfectly with the action on screen, bridging the gap between hardware and software.

It’s no longer just an iPhone. It’s your childhood, reborn in your pocket.
