What it does
Delta provides retro-game emulation on Apple mobile devices. Its official guide covers installation, games and related reading or setup topics.
Follow the installation route offered for your country and device before importing a permitted game file. The user guide is the right place to check system files, controller setup and synchronization. Delta is an emulator, so the application itself should not be mistaken for a store granting a retro-game catalogue.
The current Get Delta guide directs EU users to AltStore PAL and readers outside the EU to the App Store. Once installed, tap + at the top-right of the library to import your game file. Match the extension to the system; the guide lists .gba for Game Boy Advance and .nds or .ds for Nintendo DS, among others.
