Some diehard fans of retro games are heartbroken about the recent announcement from DolphinOS, a leading emulator for the Nintendo Wii and GameCube games, that it will not release any versions for the Apple App Store.

DolphiniOS confronted Apple's latest regulation enabling game emulators by only detailing that the limitations prevailing on its underlining technology were the main reason it had very little chance to continue using it.

The JIT Complication

The heart of the matter lies in Apple's prohibition of DolphiniOS and similar emulators from utilizing Just-in-Time (JIT) compilers, as elucidated by developer OatmealDome. JIT compilers play a pivotal role in translating the PowerPC-based code of GameCube and Wii games into a language compatible with modern ARM-based CPUs, thereby ensuring smooth emulation performance.

Despite DolphiniOS's attempt to secure JIT support through a Digital Markets Act (DMA) interoperability request, Apple declined the plea. The rejection effectively renders DolphiniOS unable to leverage its optimal performance capabilities on Apple devices.

While alternatives like using an interpreter exist, they result in significantly inferior emulation performance, as demonstrated in comparison videos shared by OatmealDome.

The unfortunate consequence is the unavailability of DolphiniOS for iOS users, depriving them of the opportunity to experience classic Nintendo titles on their devices. While Apple's policy shift was a step forward for retro gaming emulation, the standoff between DolphiniOS and Apple underscores the challenges inherent in navigating the intersection of technology, legality, and user experience.

The Implications

The essence of the problem is that there is no compatibility between the PowerPC electronics of GameCube and Wii consoles and the ARM-based hardware of modern Apple devices. The JIT isn't allowed to replace the ARD in a JIT-compliant OS. As the DolphiniOS relies on auto recompilers, being an ARD-compliant OS, JIT restrictions present the other formidable obstacle for the team.

Today, supporters of DolphiniOS can either resort to gathering methods like jailbreaking or use an app store that is not the Apple one, such as AltStore, to use the operating system. Nevertheless, the lack of some decision from Apple regarding the emulation technology forced the future of this project for GameCube and Wii emulation on iOS devices into a problematic state.

The Delta Contrast

The saga of DolphiniOS mirrors the broader landscape of retro gaming emulation on iOS devices following Apple's revised App Review Guidelines. While the arrival of the Delta emulator on the App Store marked a milestone, allowing emulation of NES, Game Boy, N64, and DS games, DolphiniOS remains sidelined due to its dependence on JIT technology.

As the gaming community holds its collective breath in the midst of DolphiniOS's heroic battle against Apple's complex restrictions, it hopes for a breakthrough that will clear the way and allow the beloved emulator entry to the App Store. Even when the horizon darkens, and uncertainty casts shadows, fans hold out hope for a victorious conclusion.

Users will travel other paths in hope until that fatal day arrives, and the discussion of whether or not retro game emulation on iPhones will continue reverberating within the gaming community.
