OSFMount / exFAT
- Improved OSFMount detection across native 64-bit and 32-bit Program Files, both registry views, custom installation paths, PATH and portable layouts.
- Added Browse and Auto controls in exFAT → PKG; manual OSFMount selections are remembered.
- Selecting OSFMount.exe resolves to the console program in the same folder.
- Clearer missing-tool and driver/admin error messages, retaining read-only mounting and mount ownership/cleanup checks.
PKG file editor
- New Extract file from PKG section: browse supported package contents and extract selected files.
- Import replacements or new files, remove optional entries and restore staged changes.
- Save a small edit project, rebuild a separate full PKG or create an SDK update.
- Versions use NN.NNN.NNN, such as 01.001.005.
- Fixed large supplemental data triggering the false 256 MiB CNT metadata error.
Installation and limits
Extract the complete ZIP and launch START.cmd. The launcher compiles the application for Windows on first launch.
Browsing, selected extraction and saving edit projects avoid a full dump. Full-PKG and SDK-update creation still process the full source and require temporary space. The small edit project is not installable.
C# 5 compilation and local regression tests passed. Actual OSFMount mounting on Windows and console compatibility remain unverified.
