: The tool can maintain a database to keep track of these streams, which helps in efficient deduplication and recompression during the final packing phase.
Original EXE (game.exe) ↓ [Calculate CRC32] ↓ [Compare with xdelta patch] ↓ [Apply modifications byte-by-byte] ↓ Patched EXE (bypasses DRM)
: Once the data is raw, users can apply heavy-duty compressors (like 7-Zip’s LZMA2 or Zstd) to achieve much higher ratios than the original game files. Reconstruction
: After XTool finishes, the resulting "precompressed" file is typically passed through a high-ratio compressor to reach its final, tiny repack size. Is XTool Safe?
In 2014–2015, razor12911 began writing a set of tools in C++ and assembly (for critical hot paths). The result was — not a single program, but a collection of utilities and a core decompression engine:
