IOS is the Wii's internal operating system running on an ARM coprocessor. Games run on the bare metal but rely on IOS for essential services like DI, USB and power state management.
The information on this page only holds for the latest development version. Older versions have worse emulation.
# Emulation
Dolphin does not emulate the Starlet coprocessor at all, except the IPC registers, which are however hardcoded to be routed to IOS HLE. This means that Dolphin is unable to run any IOS or anything running on the Starlet, and instead HLEs IOS. This works fine with anything that doesn't rely on raw hardware access or patching IOS.
