ARMCore::SetMMUFaultsEnabled(true) makes the Starlet core deliver the faults of the ARM926EJ-S MMU instead of the identity fallback: - translation (section 0x5, page 0x7), domain (0x9, 0xb) and permission (0xd, 0xf) faults from the descriptors, the DACR (no access and the reserved value fault; manager skips AP) and AP with the S and R bits; ARMv5 has no execute permission, so a fetch needs read permission; - data aborts (vector 0x10, LR = instruction + 8 in both states) set the FSR and the FAR (the MVA); prefetch aborts (vector 0x0c, LR + 4) set the IFSR (c5 opcode2 1) and leave the FAR unchanged; - alignment faults (0x1) when control bit A is set; - base-restored data aborts: the first faulting access ends the instruction's bus traffic and its register results are undone; words stored before the fault stay written; - LDRT/STRT/LDRBT/STRBT check User permissions in any mode; - the TLB keeps each granule's domain and AP, never caches a faulting walk, and c8 single-entry operations drop only the page that maps the MVA, so an entry stays stale until the guest invalidates it; - MRC/MCR to CP15 from User mode is an undefined instruction. The JIT stays usable: with the option on, every block entry goes through C++, which checks the fetch under the current mode and DACR, and only instructions that touch neither memory, CP15, the PSRs nor the exception model run natively; the rest use the interpreter. Off by default. The IOS LLE path keeps its identity fallback, its savestate format (the option and the IFSR are not serialized) and its idle-loop fast-forwarding; the only change there is that the data accessors read one abort flag that stays clear. 20 StarletARMCoreMMUFaults tests, each run in the interpreter and the JIT; the existing Starlet tests pass unchanged.

Dolphin - A GameCube and Wii Emulator
Homepage | Project Site | Buildbot | Forums | Wiki | GitHub Wiki | Issue Tracker | Coding Style | Transifex Page | Analytics
Dolphin is an emulator for running GameCube and Wii games on Windows, Linux, macOS, and recent Android devices. It's licensed under the terms of the GNU General Public License, version 2 or later (GPLv2+).
Please read the FAQ before using Dolphin.
System Requirements
Desktop
- OS
- Windows (10 1903 or higher).
- Linux.
- macOS (11.0 Big Sur or higher).
- Unix-like systems other than Linux are not officially supported but might work.
- Processor
- A CPU with SSE2 support.
- A modern CPU (3 GHz and Dual Core, not older than 2008) is highly recommended.
- Graphics
- A reasonably modern graphics card (Direct3D 11.1 / OpenGL 3.3).
- A graphics card that supports Direct3D 11.1 / OpenGL 4.4 is recommended.
Android
- OS
- Android (7.0 Nougat or higher).
- Processor
- A processor with support for 64-bit applications (either ARMv8 or x86-64).
- Graphics
- A graphics processor that supports OpenGL ES 3.0 or higher. Performance varies heavily with driver quality.
- A graphics processor that supports standard desktop OpenGL features is recommended for best performance.
Dolphin can only be installed on devices that satisfy the above requirements. Attempting to install on an unsupported device will fail and display an error message.
Building
You may find building instructions on the appropriate wiki page for your operating system:
Before building, make sure to pull all submodules:
git submodule update --init --recursive
Android-specific instructions
These instructions assume familiarity with Android development. If you do not have an Android dev environment set up, see AndroidSetup.md.
If using Android Studio, import the Gradle project located in ./Source/Android.
Android apps are compiled using a build system called Gradle. Dolphin's native component, however, is compiled using CMake. The Gradle script will attempt to run a CMake build automatically while building the Java code.
Uninstalling
On Windows, simply remove the extracted directory, unless it was installed with the NSIS installer, in which case you can uninstall Dolphin like any other Windows application.
Linux users can run cat install_manifest.txt | xargs -d '\n' rm as root from the build directory
to uninstall Dolphin from their system.
macOS users can simply delete Dolphin.app to uninstall it.
Additionally, you'll want to remove the global user directory if you don't plan on reinstalling Dolphin.
Command Line Usage
Usage: Dolphin.exe [options]... [FILE]...
Options:
--version show program's version number and exit
-h, --help show this help message and exit
-u USER, --user=USER User folder path
-m MOVIE, --movie=MOVIE
Play a movie file
-e <file>, --exec=<file>
Load the specified file
-n <16-character ASCII title ID>, --nand_title=<16-character ASCII title ID>
Launch a NAND title
-C <System>.<Section>.<Key>=<Value>, --config=<System>.<Section>.<Key>=<Value>
Set a configuration option
-s <file>, --save_state=<file>
Load the initial save state
-d, --debugger Show the debugger pane and additional View menu options
-l, --logger Open the logger
-b, --batch Run Dolphin without the user interface (Requires
--exec or --nand-title)
-c, --confirm Set Confirm on Stop
-v VIDEO_BACKEND, --video_backend=VIDEO_BACKEND
Specify a video backend
-a AUDIO_EMULATION, --audio_emulation=AUDIO_EMULATION
Choose audio emulation from [HLE|LLE]
Available DSP emulation engines are HLE (High Level Emulation) and LLE (Low Level Emulation). HLE is faster but less accurate whereas LLE is slower but close to perfect. Note that LLE has two submodes (Interpreter and Recompiler) but they cannot be selected from the command line.
Available video backends are "D3D" and "D3D12" (they are only available on Windows), "OGL", and "Vulkan". There's also "Null", which will not render anything, and "Software Renderer", which uses the CPU for rendering and is intended for debugging purposes only.
