Dolphin Issue 6784, readme.txt with OS X info

Dolphin - A Gamecube / Triforce / Wii Emulator
==========================================
Homesite: http://dolphin-emu.org/
Project Site: http://code.google.com/p/dolphin-emu

Dolphin is an emulator for running Gamecube, Triforce and Wii games on
Windows/Linux/OS X systems and recent Android devices. It's licensed under
the terms of the GNU General Public License, version 2 (GPLv2).

Please read the FAQ before use: http://dolphin-emu.org/docs/faq/

[System Requirements]
* OS: Microsoft Windows (XP/Vista or higher) or Linux or Apple Mac OS X (10.7 or higher).
  Windows XP x64 is NOT supported.
  Unix like systems other than Linux might work but are not officially supported.
* Processor: A CPU with SSE2 support
  At least 3 GHz and Dual Core highly recommended.
* Graphics: A reasonably modern graphics card (Direct3D 10.0 / OpenGL 3.0).
  Direct3D 11 / OpenGL 4.4 recommended.

[Installation on Windows]
Use the solution file Source/dolphin-emu.sln to build Dolphin on Windows.
Visual Studio 2013 is a hard requirement since previous versions don't support
many C++ features that we use. Other compilers might be able to build Dolphin
on Windows but have not been tested and are not recommended to be used.

An installer can be created by using the Installer_win32.nsi and
Installer_x64.nsi scripts in the Installer directory. This will require the
Nullsoft Scriptable Install System (NSIS) to be installed. Creating an
installer is not necessary to run Dolphin since the Build directory contains
a working Dolphin distribution.

[Installation on Linux/OS X]

Dolphin requires CMake for systems other than Windows. Many libraries are
bundled with Dolphin and used if they're not installed on your system. CMake
will inform you if a bundled library is used or if you need to install any
missing packages yourself.

Build steps:
mkdir Build
cd Build
cmake ..
make

On OS X, a .app bundle will be created in ./Binaries.

On Linux, it's strongly recommended to perform a global installation of Dolphin.
sudo make install

[Uninstalling]
When Dolphin has been installed with the NSIS installer, you can uninstall
Dolphin like any other Windows application.

Linux users can run "cat install_manifest | xargs rm" from the build directory
to uninstall Dolphin from their system.

OS X users can simply delete Dolphin.app to uninstall it.

Additionally, you'll want to remove the global user directory (see below to
see where it's stored) if you don't plan to reinstall Dolphin.

[Command line usage]
Usage: Dolphin [-h] [-d] [-l] [-e <str>] [-b] [-V <str>] [-A <str>]
  -h, --help                   Show this help message
  -d, --debugger               Opens the debugger
  -l, --logger                 Opens the logger
  -e, --exec=<str>             Loads the specified file (DOL,ELF,WAD,GCM,ISO)
  -b, --batch                  Exit Dolphin with emulator
  -V, --video_backend=<str>    Specify a video backend
  -A, --audio_emulation=<str>  Low level (LLE) or high level (HLE) audio

Available DSP emulation engines are HLE (High Level Emulation) and
LLE (Low Level Emulation). HLE is fast but often less accurate while LLE is
slow but close to perfect. Note that LLE has two submodes (Interpreter and
Recompiler), which cannot be selected from the command line.

Available video backends are "D3D" (only available on Windows Vista or higher),
"OGL". There's also "Software Renderer", which uses the CPU for rendering and
is intended for debugging purposes, only.

[Sys Files]
totaldb.dsy: Database of symbols (for devs only)
GC/font_ansi.bin: font dumps
GC/font_sjis.bin: font dumps
GC/dsp_coef.bin: DSP dumps
GC/dsp_rom.bin: DSP dumps

The DSP dumps included with Dolphin have been written from scratch and do not
contain any copyrighted material. They should work for most purposes, however
some games implement copy protection by checksumming the dumps. You will need
to dump the DSP files from a console and replace the default dumps if you want
to fix those issues.

[Folder structure]
These folders are installed read-only and should not be changed.

GameSettings: per-game default settings database
GC: DSP and font dumps
Maps: symbol tables (dev only)
OpenCL: OpenCL code
Shaders: post-processing shaders
Themes: icon themes for GUI
Wii: default Wii NAND contents

[User folder structure]
A number of user writeable directories are created for caching purposes or for
allowing the user to edit their contents. On OS X and Linux these folders are
stored in ~/Library/Application Support/Dolphin/ and ~/.dolphin-emu respectively.
On Windows the user directory is stored in the "My Documents" folder by default,
but there are various way to override this behavior:
- Creating a file called "portable.txt" next to the Dolphin executable will
  store the user directory in a local directory called "User" next to the
  Dolphin executable.
- If the registry string value "LocalUserConfig" exists in
  "HKEY_CURRENT_USER/Dolphin Emulator" and has the value "1", Dolphin will
  always start in portable mode.
- If the registry string value "UserConfigPath" exists in
  "HKEY_CURRENT_USER/Dolphin Emulator", the user folders will be stored in the
  directory given by that string. The other two methods will be prioritized
  over this setting.

List of user folders:
Cache: used to cache the ISO list
Config: configuration files
Dump: anything dumped from dolphin
GameConfig: additional settings to be applied per-game
GC: memory cards
Load: custom textures
Logs: logs, if enabled
ScreenShots: screenshots taken via Dolphin
StateSaves: save states
Wii: Wii NAND contents

[Custom textures]
Custom textures have to be placed in the user directory under
Load/Textures/<GameID>/. You can find the Game ID by right-clicking a game
in the ISO list and selecting "ISO Properties".
