The "Release" solution configuration includes performance optimizations for the best user experience but complicates debugging Dolphin.
The "Debug" solution configuration is significantly slower, more verbose and less permissive but makes debugging Dolphin easier.
An installer can be created by using the `Installer.nsi` script in the
Installer directory. This will require the Nullsoft Scriptable Install System

## Uninstalling
When Dolphin has been installed with the NSIS installer, you can uninstall
Dolphin like any other Windows application.
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 (see below to
see where it's stored) if you don't plan to reinstall Dolphin.

## Sys Files
## DolphinTool Usage
```
usage: dolphin-tool COMMAND -h
* `wiitdb.txt`: Wii title database from [GameTDB](https://www.gametdb.com/)
* `totaldb.dsy`: Database of symbols (for devs only)
* `GC/font_western.bin`: font dumps
* `GC/font_japanese.bin`: font dumps
* `GC/dsp_coef.bin`: DSP dumps
* `GC/dsp_rom.bin`: DSP dumps
* `Wii/clientca.pem`: Wii network certificate
* `Wii/clientcakey.pem`: Wii network certificate key
* `Wii/rootca.pem`: Wii network certificate issuer / CA
commands supported: [convert, verify, header]
```
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.
```Usage: convert [options]... [FILE]...
Wii network certificates must be extracted from a Wii IOS. A guide for that can be found [here](https://wiki.dolphin-emu.org/index.php?title=Wii_Network_Guide).
Options:
-h, --help show this help message and exit
-u USER, --user=USER User folder path, required for temporary processing
files.Will be automatically created if this option is
not set.
-i FILE, --input=FILE
Path to disc image FILE.
-o FILE, --output=FILE
Path to the destination FILE.
-f FORMAT, --format=FORMAT
Container format to use. Default is RVZ. [iso|gcz|wia|rvz]
-s, --scrub Scrub junk data as part of conversion.
-b BLOCK_SIZE, --block_size=BLOCK_SIZE
Block size for GCZ/WIA/RVZ formats, as an integer.
Suggested value for RVZ: 131072 (128 KiB)
-c COMPRESSION, --compression=COMPRESSION
Compression method to use when converting to WIA/RVZ.
Suggested value for RVZ: zstd [none|zstd|bzip|lzma|lzma2]
-l COMPRESSION_LEVEL, --compression_level=COMPRESSION_LEVEL
Level of compression for the selected method. Ignored
if 'none'. Suggested value for zstd: 5
```
## Folder Structure
```
Usage: verify [options]...
These folders are installed read-only and should not be changed:
Options:
-h, --help show this help message and exit
-u USER, --user=USER User folder path, required for temporary processing
files.Will be automatically created if this option is
not set.
-i FILE, --input=FILE
Path to disc image FILE.
-a ALGORITHM, --algorithm=ALGORITHM
Optional. Compute and print the digest using the
selected algorithm, then exit. [crc32|md5|sha1]
```
* `GameSettings`: per-game default settings database
* `GC`: DSP and font dumps
* `Shaders`: post-processing shaders
* `Themes`: icon themes for GUI
* `Resources`: icons that are theme-agnostic
* `Wii`: default Wii NAND contents
```
Usage: header [options]...
## Packaging and udev
The Data folder contains a udev rule file for the official GameCube controller
adapter and the Mayflash DolphinBar. Package maintainers can use that file in their packages for Dolphin.
Users compiling Dolphin on Linux can also just copy the file to their udev
rules folder.
## User Folder Structure
A number of user writeable directories are created for caching purposes or for
allowing the user to edit their contents. On macOS and Linux these folders are
stored in `~/Library/Application Support/Dolphin/` and `~/.dolphin-emu`
respectively, but can be overwritten by setting the environment variable
`DOLPHIN_EMU_USERPATH`. 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/Software/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/Software/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 and system BIOS
* `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".
Options:
-h, --help show this help message and exit
-i FILE, --input=FILE
Path to disc image FILE.
-b, --block_size Optional. Print the block size of GCZ/WIA/RVZ formats,
then exit.
-c, --compression Optional. Print the compression method of GCZ/WIA/RVZ
formats, then exit.
-l, --compression_level
Optional. Print the level of compression for WIA/RVZ
formats, then exit.
