Learn what JIT is and how to enable it on your device.
What is JIT?
JIT, or Just in Time, is a technique used by Dolphin (the emulator) to emulate the GameCube and Wii's CPU at fast speeds. Without JIT, Dolphin would run at unplayably slow frame rates. However, on non-jailbroken iOS devices, an app cannot use JIT by default.
How to Enable JIT on DolphiniOS
There are a few different ways to enable JIT on DolphiniOS. Here are two options:
- AltJIT: AltJIT is automatically attempted when starting a game if DolphiniOS is installed using AltStore. However, your iPhone or iPad must be connected to the same Wi-Fi network as the PC or Mac that AltServer is installed on for AltJIT to work. For more information, see the AltJIT guide.
- JitStreamer: JitStreamer is a service that allows you to activate JIT on DolphiniOS wherever a Wi-Fi network is available. A computer is not required. Instructions on how to set up JitStreamer can be found on its website. For more information, visit its website.
