Delta Patcher is a hybrid front end to the xdelta3 decoder/encoder. It embeds the xdelta.exe executable and extracts it on the fly to apply/create xdelta patches.
It supports more options than the most front ends, like compression level, source window size, patch descriptions and checksum verification. It's written in C++ and all the needed libraries are statically linked to the EXE.
Last, but not the least, Delta Patcher is cross-platform: it runs fine on Windows and Linux and should compile on MacOS too.
Features
- No xdelta.exe is needed.
- Intuitive GUI design.
- Multiple options for patch application/creation.
- Associate xdelta patch files to be opened with delta patcher.
- Drag & Drop support for original file and xdelta patch file in the decoding window.
- Cross-platform and opensource.
- Multilanguage.
Installation
This package comes with two versions of the frontend.
- Lite - Contain just the patching GUI, this is intended to be shipped along with your patch and to keep it simple for final users.
- Full - Mainly for romhackers, it supports both creation and application of xdelta patches.
User guide
Patch options
Patch application:
- Disable checksum validation.
- Backup original file.
Patch creation:
- Patch compression level.
- Source window size.
- Checksum.
- Custom UTF8 description for patches. Patches created with delta patcher will show this description if opened with delta patcher (a là PPF-O-MATIC3).
Multilanguage
Delta Patcher can be translated into any language using .po files.
If you want multilanguage support you have to place the resource directory along with this tool (see source code for the pot file).

Changelog
v3.0.1
- Fixed memory leak when applying patches without a description.
v3.0.0
- Modernized the build system using cmake.
- xdelta has now finally been embedded as a library rather than an exe that needs to be extracted on the fly. This should finally avoid false positives from some antiviruses. In this process, xdelta has then also been updated to the latest stable version (3.0.11) which now supports secondary compressions.
- Delta Patcher now allows to select the desired secondary compression (including lzma), when in patch creation mode.
- There is no more distinction between lite and full versions. This separation was quite redundant and unnecessary (the only difference was in one button).
- Fixed an annoying bug that would prevent Delta Patcher to open some xdelta patches using secondary compression.
- The Windows exe is still fully self-contained and compatible with Windows XP or above.
- To avoid further false positive from anti virus software, the windows exe is not compressed anymore, so it is a bit larger than version 2.
v2.0.1
- Added drag and drop functionality in patch creation mode.
v2.0
- Major updates to GUI design, features and linux compatibility.
- Most importantly, no xdelta.exe is needed starting from this version.
v1.0
- Stable release.
