v2.7.1

v2.7.1 is a bugfix release, mostly for issues on Windows for ARM systems.

Major additions in v2.7 include:

• Android packages. Supports thumbnailing packages that use PNG icons. WebP icons are also supported if libwebp is installed.

  • Packages that use "adaptive icons" are not currently thumbnalied.

• Nintendo 3DS: Z3DS compressed format is now supported.

• Windows and GNOME Nautilus (and Caja and Nemo): In Details view, rom-properties now provides columns for some properties, including "Game ID" and "Title ID".

• GNOME Nautilus (and Caja and Nemo): An emblem is now shown for files with potentially dangerous permissions.

• Windows-specific changes:

  • Installers are now created using Inno Setup instead of the custom svrplus executable. Both Inno Setup 5 and 6 are used:
    • Inno Setup 5 is used for Windows XP, 2003, and Vista.
    • Inno Setup 6 is used for Windows 7, 8.x, 10, and 11.
  • ~~The arm64 and arm64ec DLLs have been combined using Microsoft's ARM64X format.~~ This isn't working properly; it will be reverted to ARM64-only for v2.7.1.
  • Add special handling for 16-bit executables and Windows 1.x/2.x icons. This is implemented using Microsoft's Detours library, and currently only works once rom-properties.dll is loaded in the Explorer process. (View the "ROM Properties" tab of a supported file to load it.)
  • Localization via GNU gettext is now available on ARM and ARM64.

• Lots and lots of tiny bug fixes and improvements.

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.)

See NEWS.md for a full list of changes in v2.7.1.

Installation

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

• KDE Frameworks 5.x and 6.x (Dolphin and Konqueror)
• XFCE (Thunar)
• GNOME 3.x through 42 (Nautilus)
• GNOME 43 (Nautilus)
• MATE Desktop (1.18+) (Caja)
• Cinnamon Desktop (Nemo)
• Windows 7 (and later)

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

• KDE 4.x
• Windows XP SP3, Windows Server 2003 SP2, Windows Vista
  • Note that WinInet in older versions of Windows does not support the newer encryption algorithms used by the online database hosts. To work around this, you will need to download an older version of cURL and a certificate bundle. This is available on the Releases page.

On Windows Vista and later, you will need the MSVC 2015-2026 runtime:

• i386 (32-bit): https://aka.ms/vs/18/release/VC_redist.x86.exe
• amd64 (64-bit): https://aka.ms/vs/18/release/VC_redist.x64.exe
• arm32: https://rpdb.gerbilsoft.com/redist/VC_redist.arm.vs2017.exe
• arm64: https://aka.ms/vs/18/release/vc_redist.arm64.exe

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

• i386 (32-bit): https://aka.ms/vs/15/release/VC_redist.x86.exe
• amd64 (64-bit): https://aka.ms/vs/15/release/VC_redist.x64.exe

For instructions on compiling from source, see doc/COMPILING.md.

Linux

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.

Windows

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.

Other

| System | Properties Tab | Metadata | Internal Images | External Scans | |:------------------------------:|:--------------:|:--------:|:---------------:|:--------------:| | Executable and Linkable Format | Yes | No | N/A | N/A | | PUC Lua binaries | Yes | No | N/A | N/A | | Mach-O Binaries | Yes | No | N/A | N/A | | Nintendo amiibo | Yes | No | N/A | Media | | Nintendo Badge Arcade | Yes | Yes | Image | N/A | | Windows/DOS Executables | Yes | Yes | Icon¹ | N/A |

• 1: Icon thumbnailing is disabled for ICO, CUR, and EXE files to prevent conflicts with system icon handling.

General notes for all formats:

• 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 GameTDB.com 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, a plush, or a wooden block.
• 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. GameTDB.com. 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:

[Keys]
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.

License

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

• PugiXML: MIT
• 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.

The original version of the "Happy Wii U" icon used for Wii U firmware binaries was provided by Vixy under CC-BY licensing. The original icon was modified to fit in a 48x48 icon frame and to provide additional information, e.g. retail vs. development (green), and to show an SD card for sdboot.

The flag icons used for region/language selection are based on flag icons from Twemoji 12.0.1. Copyright 2019 Twitter, Inc and other contributors; licensed under CC-BY 4.0.
