KDE Dolphin showing a Commodore 1541 disk image from GEOS.

Major changes in v2.3 include:

  • xattrs tab on Linux now shows XFS attributes.

  • rpcli now supports extracting mipmap levels from most supported texture formats.

    • Mipmaps are now supported for DirectDrawSurface and KhronosKTX.
  • Windows: Dark Mode is now supported on Windows 10 1809 and later in the installation program and rp-config.

    • Dark Mode is also partially supported in the properties pages when using tools such as StartAllBack, though it has some issues right now.
  • Sparse disc images, e.g. CISO and GCZ, are now handled by the RomDataFactory class instead of requiring each RomData subclass to handle it. This means that all supported sparse disc images can be used for any console.

    • This was originally implemented to support ZISO and PSP CISO for PS2 disc images, but it also allows unusual combinations like DAX and JISO for GameCube disc images.
  • Windows Image files (.wim) are now supported. Contributed by @ecumber.

  • Game Boy now has special handling MMC01 and MBC1M multicarts. The main header is now detected correctly and used for the thumbnail image. All games in the multicart are now shown as individual tabs.

  • Commodore DOS disk images (e.g. for Commodore 1541) are now supported, including icons for GEOS files. File formats supported currently include D64, D71, D80, D82, D81, D67, G64, and G71.

  • ColecoVision ROM images are now supported, including the text displayed on the ColecoVision logo screen.

  • Intellivision ROM images are now supported, including the game title and copyright year.

  • New translations: Romanian and Italian

Translators wanted; if you can translate rom-properties from English to another language, check out the Crowdin project. (If you would like to translate to a language not currently listed on the Crowdin project page, file an issue here on GitHub with the requested language.)

Currently, the ROM Properties Page shell extension is compatible with the following platforms:

  • KDE Frameworks 5.x and 6.x
  • XFCE (GTK+ 2.x, GTK+ 3.x)
  • GNOME and Unity (GTK+ 3.x)
  • GNOME 43 (GTK 4.x)
  • MATE Desktop (1.18+; GTK+ 3.x)
  • Cinnamon Desktop
  • Windows 7 (and later)

The following platforms are still compatible, but may not receive as much support:

  • KDE 4.x
  • Windows XP, Windows Server 2003, Windows Vista

On Windows Vista and later, you will need the MSVC 2015-2022 runtime:

On Windows XP/2003 and earlier, you will need the MSVC 2015-2017 runtime:

For instructions on compiling from source, see doc/


Install the relevant .deb package, depending on what desktop environment you are using and what your CPU is.

After installing, the plugin needs to be enabled in the Dolphin file browser:

  • Close all instances of Dolphin.
  • Start Dolphin.
  • Click Control, Configure Dolphin.
  • Click the "General" section, then the "Preview" tab.
  • Check the "ROM Properties Page" item, then click OK.
  • Enable previews in a directory containing a supported file type.

If installed correctly, thumbnails should be generated for the supported file type. You can also right-click a file, select Properties, then click the "ROM Properties" tab to view more information about the ROM image.


Extract the ZIP archive to a directory, then run install.exe. The installer requires administrator access, so click "Yes" if requested. In the installer, click the "Install" button to register the ROM Properties Page DLL.

Note that this will hard-code the location of the DLL files in the registry, so you may want to place the DLLs in a common location.

To uninstall the plugin, run install.exe again, then click the "Uninstall" button.

  • Internal image refers to artwork contained within the ROM and/or disc image. These images are typically displayed on the system's main menu prior to starting the game.
    • "N/A" here means the ROM or disc image doesn't have this feature.
    • "No" indicates that the feature is present but not currently implemented.
  • External scans refers to scans from an external database, such as for GameCube and Wii.
    • "No" indicates no database is currently available for this system.
    • Anything else indicates what types of images are available.
    • For amiibo, "media" refers to the amiibo object, which may be a figurine, a card, or a plush.
  • Windows executables may contain multiple icon sizes. Support for Windows icons will be added once support for multiple image sizes is added.
  • Sega 8-bit only supports ROM images with a "TMR SEGA" header.

A configuration program, rp-config, is available to configure rom-properties using a graphical interface. This program allows you to configure which images will be used for thumbnails on each system, as well as other functionality.

External Media Downloads

Certain parsers support the use of external media scans through an online database, e.g. This is enabled by default, but you can customize which scans are downloaded for which systems by running the configuration program, rp-config.exe.

Downloaded images are cached to the following directory:

  • Linux: ~/.cache/rom-properties/
  • Windows XP: %LOCALAPPDATA%\rom-properties\cache
  • Windows Vista+: %USERPROFILE%\AppData\LocalLow\rom-properties\cache

The directory structure matches the source site, so e.g. a disc image of Super Smash Bros. Brawl would be downloaded to ~/.cache/rom-properties/wii/disc/US/RSBE01.png. Note that if the download fails for any reason, a 0-byte dummy file will be placed in the cache, which tells the shell extension not to attempt to download the file again. [FIXME: If the download fails due to no network connectivity, it shouldn't do this.]

If you have an offline copy of the GameTDB image database, you can copy it to the ROM Properties Page cache directory to allow the extension to use the pre-downloaded version instead of downloading images as needed.

Decryption Keys

Some newer formats, including Wii disc images, have encrypted sections. The shell extension includes decryption code for handling these images, but the keys are not included. To install the keys, create a text file called keys.conf in the rom-properties configuration directory:

  • Linux: ~/.config/rom-properties/keys.conf
  • Windows: %APPDATA%\rom-properties\keys.conf

The keys.conf file uses INI format. An example file, keys.conf.example, is included with the shell extension. This file has a list of all supported keys, with placeholders instead of the actual key data. For example, a keys.conf file with the supported keys for Wii looks like this:

rvl-common=[Wii common key]
rvl-korean=[Wii Korean key]

Replace the key placeholders with hexadecimal strings representing the key. In this example, both keys are AES-128, so the hexadecimal strings should be 32 characters long.

NOTE: If a key is incorrect, any properties dialog that uses the key to decrypt data will show an error message instead of the data in question.

Nintendo DS Secure Area

To encrypt or decrypt the Nintendo DS Secure Area, the Blowfish key must be named nds-blowfish.bin and placed in the same directory as keys.conf.

Unsupported File?

If you have a file that you believe should be supported by ROM Propeties, or would like to see support added for a new type, file an issue on GitHub:


ROM Properties is licensed under the GNU General Public License v2. Some bundled components have other licenses:

  • basisu_astc: Apache License 2.0
  • googletest: BSD 3-clause
  • GCR_CMake: GPL-3
  • inih: BSD-3-clause
  • libmspack-xenia: LGPL-2.1
  • lz4: BSD 2-clause for lib/; GPLv2 for others
  • microtar: MIT
  • minizip-ng: zlib
  • PowerVR: MIT
  • rapidjson: MIT
  • TinyXML2: BSD 3-clause
  • unice68: GPL-3
  • uniwidth: LPGL-2.1+
  • zlib-ng: zlib
  • zstd: BSD 3-clause

GCR_CMake is only used at build time, and is only necessary for the GTK builds, so I believe it does not make the entire program GPL-3 licensed.

unice68 is linked in during compile time, but can be disabled. All builds with unice68 are therefore GPL-3+. unice68 is only used for Atari ST SNDH files, so this can be disabled if a GPL-2+ build is desired: -DENABLE_UNICE68=OFF

On Windows, the following bundled components are also used:

  • GNU gettext: GPL-3+
  • libwin32darkmode: GPL-3+

While the use of gettext can be disabled with -DENABLE_NLS=OFF, libwin32darkmode is currently always enabled, so Windows builds are always GPL-3+ at the moment.
