AI agent skills help D2R Mobile port Switch Diablo II to iPhone and iPad
On October 12, 2026, an open-source project called D2R Mobile went viral on GitHub, reportedly gaining more than 2,600 stars and 850 forks in three days. Its developer ported the Nintendo Switch version of Diablo II: Resurrected to iPhone, iPad and Apple Silicon Macs by executing ARM64 native code, using static binary rewriting and a compatibility layer, and remapping the Switch's NVN graphics API to Apple's Metal, reusing shader-conversion components from the Switch emulator Ryujinx. According to the developer's tests, an iPhone 17 Pro Max runs the game at 60 FPS, and an A16-based iPhone 14 Pro Max with 6GB of RAM reached the same frame rate, while a closed test across 44 iPhones and iPads completed the Normal, Nightmare and Hell difficulties. The project also ships Agent Skills for Claude Code and Codex that encode environment setup, asset conversion, compilation and deployment as task specifications an AI agent can follow, letting users state build goals in natural language. The article also examines the commercial impact on Blizzard and Nintendo and possible DMCA and console-key legal risks.
It shows AI coding agents taking over reverse-engineering and porting work that once required sustained expert engineering, lowering the barrier while raising copyright and legal questions.
