Check your Apple device

A17 Pro or later / M-series iPad

No extra texture conversion. Examples include iPhone 15 Pro and iPhone 16 or later; the regular iPhone 15 is on the older-device route.

A14–A16 iPhone / iPad

Requires a Legacy Device Pack made from your own game files on a computer. The author reports results for selected models; meeting the A14 minimum does not establish compatibility or a particular frame rate for every device.

Devices with 4 GB memory

Memory is tight and the system may close the app. The author reports short play on iPad mini 6 with memory warnings; this is not a stability guarantee.

Apple silicon Mac

Build a native Mac app from source; local signing needs no developer account. The Mac guide reviewed on 28 October says it depends on the original build workspace, so keep that workspace in place. It still distinguishes automated checks from unverified human operation of keyboard, physical gamepad, resource-folder dialog and menu controls. A report of older-API Mac play does not verify every setup.

Unsupported or preview hardware

A13 and earlier, and Intel Macs, are unsupported. Apple TV is a developer preview that has reached character selection, not verified full gameplay.

Choose a build for your system: iOS/iPadOS 26+ uses the standard build; 18–25 needs the older-interface build. Apple silicon Macs use the standard build on macOS 26+, or the older-interface build on macOS 15–25. Meeting the chip minimum (A14/M1) is not proof of tested compatibility.

iPhone/iPad setup in five steps

1. Prepare and check your own game files

   Follow the official file guide to obtain the two parts above and confirm the game version. On the Mac source-build route, ./setup.sh check reports missing requirements without making changes. Stop here if the files are not ready.

2. Choose your computer route

   Use the Mac/Xcode route or matching current source, build inputs and packaging tools. Choose the iOS 18–25 or iOS 26+ inputs for your device, then package and sign the app.

3. Older device? Make the extra textures first

   For A14–A16, generate a Legacy Device Pack from your own textures on the computer and include it when preparing the app, following the chosen release’s guide. It supplements the game resources; it does not replace them. If the app shows “One More Step for This Device”, regenerate the legacy texture pack from your own game files and rebuild the app.

4. Sign and install your personal app

   Follow the author’s Apple signing instructions. Mac/Xcode is the main route; the alternative packaging guide describes computer-built iOS packages, but signing with sideload tools remains unverified by the author. A free Apple ID needs re-signing every 7 days and has no iCloud save sync. Keep packages containing game-derived content for personal use; do not redistribute them.

5. Copy resources, then launch

   Put the 18 .data resource archives (about 5.6 GB) in a folder inside Files → On My iPhone/iPad → D2R Mobile, or copy them with Finder. If required, copy the entire Legacy Device Pack beside it. Retry in the app to see missing files. Some builds prepare graphics on first launch; this can take several minutes.
