A hex patching tool made for crackers, by crackers.
- Bundle Selection — Support for apps, VSTs, AudioUnits, frameworks, and system extensions
- Executable Discovery — Recursively scans MacOS, Frameworks, and LaunchServices directories
- Multi-Pattern Patching — Apply multiple hex patches in sequence
- Hex Notes Import — Batch import patches from formatted text
- Wildcard Support — Use
??wildcards with validation and memory preservation - Error Handling — Detailed error messages with context
- Progress Tracking — Real-time patching progress with timing
- Benchmarking — Built-in performance testing with visual results
- SIMD Optimization — Boyer-Moore-Horspool algorithm with SIMD acceleration
- Multi-threading — Parallel chunk processing for large files
- Download the latest release from here
- Mount the DMG file
- Drag
Amimod.appto your Applications folder
git clone https://github.com/EshayDev/Amimod.git
cd Amimod
# Open Amimod.xcodeproj in Xcode
# Build and archive the Amimod target
# Copy Amimod.app to /Applications- Launch Amimod
- Click "Select Bundle" to choose a target file
- Supported formats:
.app,.component,.audiounit,.vst,.vst3,.framework,.bundle,.kext,.appex - Select an executable from the dropdown list
- Find Hex: Enter the pattern to search for (eg.
48 89 E5 41 57) - Replace Hex: Enter the replacement pattern (eg.
90 90 90 90 90) - Click "Patch Hex" to apply
Use ?? to match any byte value:
Find: 48 89 ?? 5D C3
Replace: 90 90 90 90 90
Rules:
- Wildcards in "Replace Hex" preserve original bytes when corresponding "Find Hex" uses
?? - Validates wildcard combinations to prevent data corruption
Example preserving bytes:
Find: 48 8B ?? ?? ?? ?? 89
Replace: 48 8B ?? ?? ?? ?? 90
# Middle 4 bytes unchanged
When multiple matches are found:
- Shows match count before applying
- Asks for confirmation
- Limits to 50,000 matches per pattern to prevent performance issues
Import multiple patches using this format:
<find hex pattern>
to
<replace hex pattern>
Example:
x86_64:
31 C0 ?? ?? C3
to
31 C0 90 90 C3
ARM64:
?? ?? 80 52 C0 03 5F D6
to
20 00 80 52 C0 03 5F D6
To import:
- Click the Import button (📥) in the toolbar
- Paste hex notes into the editor
- Click "Import" to load and validate patches
- Click "Patch Hex" to apply all patches
The built-in benchmark tests patching performance across different scenarios:
- Click the Speedometer icon (⏱️) in the toolbar
- Tests pattern sizes from 8 to 256 bytes
- Tests with and without wildcards
- View results as charts or tables
- SIMD Instructions: Uses 16-bit and 32-bit SIMD for faster searching
- Boyer-Moore-Horspool: Optimized string searching algorithm
- Multi-threading: Parallel processing across CPU cores
- Chunk Management: Dynamic sizing based on file size
- Memory Efficiency: Handles large files without excessive RAM usage
