Not Coming
Dolphin
The popular GameCube and Wii emulator Dolphin will not be available in the App Store, as its developers said Apple will not allow the emulator to use just-in-time (JIT) compilation, and PowerPC-based games are “basically unplayable” without it:
The GameCube and Wii have a PowerPC-based CPU inside them. All modern Apple devices use an ARM-based CPU. It isn’t possible to directly run PowerPC code on an ARM CPU, and vice versa. Therefore, if we want to run a GameCube or Wii game on an iPhone, it is necessary to translate the game’s PowerPC code to ARM so that the CPU can understand it.
Dolphin uses something called a Just-in-Time (JIT) recompiler to achieve this. Whenever the emulated console wants to run game code, Dolphin will use its JIT to translate the PowerPC code to ARM, and then execute the results.
Unfortunately, Apple generally does not allow apps to use JIT recompilers on iOS.
