Red Dead Redemption 2 Runs Directly on iPhone 18 Pro: No PC or Cloud Required

Enthusiasts have managed to run the full PC version of Red Dead Redemption 2 on Apple’s flagship smartphone. The game runs locally on the iPhone 18 Pro’s hardware — no cloud gaming, no streaming from a home computer, no virtual machines. It was made possible by an early version of Madeira, an open-source compatibility layer that translates complex desktop instructions for the mobile processor on the fly. For the gaming industry, it’s a clear demonstration of the computing power of modern smartphones, which are gradually catching up to the hardware of last-generation consoles.

The Madeira project is a comprehensive environment for running Windows games (x86-64) on regular iPhones without a jailbreak. Under the hood, the system uses a combination of several translators: the FEX-Emu emulator converts x86-64 processor instructions into the ARM64 format understood by the mobile chip, while the DXMT library converts DirectX 12 graphics calls into Apple’s native Metal API.

Real-World Performance and the Overheating Problem

In a video demo from community members on Reddit, RDR2 on the iPhone 18 Pro Max delivers around 30 frames per second. However, it can’t yet be called a fully comfortable gaming experience. In heavy scenes with lots of objects, the frame rate drops to 18–25 FPS, the image suffers from graphical artifacts, and 60 frames can only be seen in the start menu. The creator of Madeira himself notes that a stable 30 FPS with correct texture rendering is an achievable goal for future updates, not a guaranteed current result.

The main obstacle to mobile gaming at this level remains the physics of the devices. In the project’s technical documentation, the developer directly identifies throttling as the primary risk. Heavy simultaneous load on the CPU and GPU quickly heats up the smartphone’s thin body. To avoid damage, iOS forcibly lowers the chip’s clock speeds, which means performance inevitably drops after a few minutes of play.

RDR2 just ran natively on an iPhone.

Not through cloud streaming.
Not through a jailbreak.
Not through JIT.

No App Store: How to Install It

Madeira remains strictly a research project in the experimental stage. The developer on the official X account warns about bugs and compatibility issues. Currently, only less demanding titles like Thumper and ULTRAKILL are considered fully playable.

Downloading the app from the App Store is impossible. The translator requires an enabled JIT (Just-In-Time) compiler through a connected debugger, which Apple’s store rules strictly prohibit. That’s why Madeira is installed manually via sideloading (AltStore or similar tools). If you use a free Apple ID, the app’s digital signature will “burn out” after seven days, after which the program has to be reinstalled — although save files are not deleted in the process.
