Yuzu: Ipa [portable]

Unlike the desktop version, which required relatively powerful x86 hardware, the iOS version aimed to leverage Apple’s custom silicon (starting with the A12 Bionic chip) to achieve playable performance. However, due to iOS’s strict sandboxing and lack of a just-in-time (JIT) compilation permission for third-party apps, the Yuzu IPA often performed poorly compared to its desktop counterpart. Its primary appeal was novelty: playing The Legend of Zelda: Tears of the Kingdom or Super Mario Odyssey natively on an iPhone, even with graphical glitches and low frame rates.

The “Yuzu IPA” compounded this problem because iOS devices lack a native cartridge slot. While a desktop user could theoretically dump a game cartridge using a specialized USB accessory, an iPhone user cannot.

In February 2024, Nintendo filed a lawsuit against Tropic Haze LLC, the developer of Yuzu, alleging not just contributory infringement but “circumvention of technological measures” under the Digital Millennium Copyright Act (DMCA).
