This branch is used for the development of the ongoing nxdumptool rewrite. Code is highly experimental and lacks a proper UI at this time, but it has been thoroughly tested and should be safe to use. Proof-of-concept (PoC) builds are provided to test different aspects of the codebase.

If a nxdumptool build from the releases page isn't working for whatever you're trying to do (e.g. RomFS dumping), odds are it will work with a PoC build from this particular branch. The old branch will not receive any further updates.

A GitHub workflow is used to automatically build each new commit -- feel free to check it out.

This readme will be updated whenever the rewrite branch is ready for a proper release.

Currently planned changes for this branch include:

• USB ABI (dump data directly to a PC). ✅
• USB Mass Storage device support (FAT, NTFS, EXT). ✅
• Gamecard header dumps. ✅
• Gamecard CardInfo area dumps. ✅
• Gamecard InitialData area dumps. ✅
• Individual NCA dumps (select and dump a specific NCA from a title). ✅
• Individual NCA FS section dumps (select and dump a specific FS section from a specific NCA belonging to a title, in both extracted and raw image forms) (this includes patched RomFS images). ✅
• System title support (e.g. dump qlaunch, shared fonts and much, much more at runtime). ✅
• Better support for NCA BucketTree storages (Indirect, AesCtrEx, Sparse, Compressed), as well as better handling of multi-layered reads in combination with game updates. ✅
• Volatile ticket dumping -- temporary tickets that are downloaded and kept in RAM instead of being written to the eMMC. ✅
• Better memory handling while dealing with compressed NRO binaries. ✅
• Event-driven background threads to manage gamecard insertions/ejections, gamecard application metadata parsing (e.g. the game would be properly identified even if its gamecard has never been used on your console), USB ABI sessions and USB Mass Storage devices. ✅
• Improved support for multigame gamecards and titles with more than one Program NCA (e.g. SM3DAS). ✅
• Control.nacp patching while dumping NSPs (lets you patch screenshot, video, user account and HDCP restrictions). ✅
• Full system update dumps. ❌
• New UI using a customized borealis fork. ⚠️
