High-Performance Xbox & Xbox 360 Disc Image Converter & Suite
Unified native support for Windows (GUI & CLI) and Android (Material 3 Dark)
XGDTool (High-Performance Fork by Ashnar2602, based on the original utility by WiredOpposite) is a modern, unified conversion and disc optimization toolchain for Original Xbox and Xbox 360 game discs.
Whether running on a multi-core Windows desktop or on an Android smartphone, XGDTool converts, scrubs, verifies, and packages disc images at maximum storage controller throughput, with zero external runtime dependencies.
- Vectorized & Hardware-Accelerated CRC32:
Native ARMv8 ACLE assembly (
__crc32d) delivering 15–20 GB/s on mobile ARM64 devices, and Slice-by-8 vectorized algorithm on x86_64 processing 8 bytes/cycle in L1 cache (4–5 GB/s per core). - Asynchronous Double-Buffering Ring Pipeline:
Prefetches uncompressed data blocks in background (
std::async) while worker threads compress the current buffer, completely hiding disk read latency behind CPU passes. - OS Storage Sequential Hints & Zero-Fragmentation Pre-allocation:
Kernel hints (
FILE_FLAG_SEQUENTIAL_SCANandPOSIX_FADV_SEQUENTIAL) and pre-allocation (posix_fallocate/resize_file) prevent disk cluster fragmentation during extraction. - Live Throughput (MB/s) & Dynamic ETA Countdown:
Accurate rolling transfer speed (
MB/s) and formatted ETA countdown (hh:mm:ss) updated in real time in both the CLI progress bar and GUI interface. - Diagnostic Image Verification Mode (
--verify/ UI Button): Non-destructive integrity scanner inspecting disc geometry (XGD2/XGD3, layer break), AVL filesystem structure, Title ID, Title Name, and streaming checksums (CRC32, MD5, SHA-1). - Smart Game Renamer (
--smart-rename/ UI Option): Automatically names output files and folders following the standard[<TitleID>] <GameName>convention. - Windows Explorer Context Menu Integration:
Instant non-elevated right-click registration (
--register-shell) for.iso,.xiso,.cso,.cci, and.zar. - Zero-Copy Android Storage Engine:
Converts directly in place via
MANAGE_EXTERNAL_STORAGEand real SAF path resolution, eliminating 15–20 GB of duplicate cache overhead. - Lock-Free Multithreaded Compression: Coarse-grained batch coordinators with atomic work-stealing saturate all CPU cores for CSO and CCI compression without mutex contention.
- Parallel Multi-Core ZArchive (Zstd): Compresses 4 MB data block batches concurrently across all CPU threads with dedicated Zstd contexts, supporting compression levels 1 through 6 while preserving ~2 GB/s emulator decompression speeds.
- Full Format Interoperability: Bidirectional conversions between ISO / XISO, CSO, CCI, GoD (Games on Demand), ZAR (ZArchive), and Extracted Loose Folders.

- Launch
XGDTool-GUI.exe. - Drag and drop any
.iso,.zar,.cso,.cci, or game folder into the window. - Select your target format (e.g.
XISO,ZAR,GoD). - Click Start to process all queued files.
# Convert an ISO to Games on Demand (GoD) format for Xbox 360 RGH
XGDTool-CLI.exe --god "D:\Games\Halo_Reach.iso" "E:\X360_USB\Content\0000000000000000"
# Convert a ZAR archive back to standard uncompressed XISO
XGDTool-CLI.exe --xiso "D:\Backups\Dantes_Inferno.zar" "D:\Extracted_ISOs"
# Reauthor an ISO with Full Scrub and calculate streaming checksums
XGDTool-CLI.exe --xiso --full-scrub --checksum "D:\Games\Game.iso"
# Convert multiple images in parallel using 8 CPU worker threads
XGDTool-CLI.exe --cso --threads 8 "D:\Games"- Install
XGDTool-Android.apkon Android 8.0+ (ARM64). - Tap Sorgente (Input) to select your disc image or folder.
- Tap Destinazione (Output) to choose your target folder.
- When prompted, enable All Files Access to activate high-speed Zero-Copy mode.
- Select your desired format and tap Avvia Conversione. The app runs as a foreground service with live notification progress.
