Usage

senbei <file|folder> [--out DIR] [-v|--verbose] [-q|--quiet]... [--scan-all] [--no-log] [--no-pause] [-V|--version] [-h|--help]

Single File

The output is written below <parent>/unpack/ with .unpack inserted before the extension. --out DIR changes both the output and log directory.

senbei app.exe
senbei app.exe --out C:\out

For global-metadata.dat, Senbei writes global-metadata.unpack.dat only when method tokens change. Unsupported metadata versions remain untouched and are reported as skipped.

Android Targets

Protected .so files are restored from their encrypted payload sections and written as libil2cpp.unpack.so or the corresponding input name. APK, APKS, and XAPK files are treated as containers: their manifests are read first, nested APKs are followed when necessary, and only .so and exact global-metadata.dat entries are extracted.

If a restored library contains embedded metadata, the unwrapped blob is written beside it as global-metadata.unpack.dat. Identical loose and package entries are restored once, preferring the loose file.

Folder Mode

Folder mode walks recursively, skips directories named unpack, and mirrors recognized outputs below <root>/unpack/ or --out DIR. Windows candidates are .exe, .dll, and global-metadata.dat; Android candidates are .so and global-metadata.dat. A matching .exe._ or .dll._ payload is consumed by its stub and is excluded from the skipped count.

The summary has the form 12 unpacked · 3 skipped · 0 errors · 1 suspect · 2 metadata; the package count is appended when packages were opened. Each file is isolated so one failed target does not stop the folder run.

Integrity Check

PE outputs are checked for valid headers, section ranges, entry-point mapping, readable import names, relocation requirements, and managed metadata signatures. Android outputs are validated during ELF restoration, including decoded container sizes, fixup bounds, and rebuilt dynamic tables.

A clean report is not a proof of correctness, but a non-clean report is a reliable broken-output signal. Suspect PE files are still written and counted separately.

Flags

Flag	Behavior
`--out DIR`	Write outputs and logs below `DIR`.
`-v`, `--verbose`	Print per-stage progress.
`-q`, `--quiet`	Hide progress and per-file lines; repeat to suppress all standard output.
`--no-log`	Do not write a run log.
`--scan-all`	Probe every selected target-name candidate, including files below the size floor.
`--no-pause`	Disable the Explorer-friendly Windows exit prompt.
`-V`, `--version`	Print the version and exit.
`-h`, `--help`	Show usage.

Exit Codes

Code	Meaning
`0`	The requested restore completed without errors.
`1`	A target failed, a scan probe was unreadable, or a single-file restore errored.
`2`	The command line was invalid.
