DolphiniOS, a fork of the favored Dolphin emulator for Nintendo Wii and GameCube video games, has confirmed that it’s not coming to the Apple App Retailer despite the fact that emulators at the moment are supported. In a post on Friday, the developer behind the emulator says it’s as a result of Apple doesn’t enable DolphiniOS to make use of its underlying performance-boosting tech.

As defined by developer OatmealDome, DolphiniOS — together with different Wii and GameCube emulators — makes use of one thing referred to as Simply-in-Time (JIT). It is a compiler that “interprets” the GameCube and Wii’s PowerPC-based code right into a language different gadgets can perceive, making emulations run lots smoother.

However Apple doesn’t enable third-party apps to make use of JIT compilers, as famous by OatmealDome. “The one exceptions are Safari and various internet browsers in Europe,” the developer writes. “We submitted a DMA [Digital Markets Act] interoperability request to Apple for JIT assist, however Apple denied the request just a few weeks in the past.”

Though there’s a approach to get round JIT through the use of an “interpreter,” OatmealDome writes that it’s “many occasions slower than the JIT compiler.” A pair of movies shared by OatmealDome reveals simply how poorly a Mario Kart Wii emulation performs on an iPhone 15 when using an interpreter as a substitute of JIT. The Verge reached out to Apple with a request for extra details about its guidelines surrounding JIT however didn’t instantly hear again.
