How to Add ROMs to Delta from the Files App
Import GBA, NDS, GBC and NES ROM files into Delta Emulator using the iOS Files app — works with any ROM you already have.
Overview
Delta Emulator doesn't ship with any games built in — it's just the player. To actually play something, you need to import a ROM file into it, and on iOS that happens through the system-wide Files app rather than iTunes or a cable, since Delta reads files straight from your device's local storage or connected cloud drives.
The process is the same regardless of console: Game Boy (.gb), Game Boy Color (.gbc), Game Boy Advance (.gba), Nintendo DS (.nds) and NES (.nes) ROMs all import the same way, and Delta automatically figures out which core to launch based on the file extension — you never have to pick a console manually.
This guide assumes Delta is already installed. If you haven't done that yet, start with our guide on installing Delta on iPhone first, then come back here.

Good to Know
If a ROM is inside a .zip file, unzip it first — tap and hold the file in Files and choose Uncompress, then import the extracted .gba/.nds/etc. file.
ROMs saved to iCloud Drive need to be fully downloaded to your device before Delta can read them — if you see a cloud icon next to the file in Files, tap it once to download, then try importing again.
Only import ROMs of games you legally own. Delta and 8bitLoft don't host or endorse piracy — save files and ROM hacks on this site are for games you already have.
