A utility to read and modify the contents of SilverDB files within iPod firmware. Tested on 5th, 6th, and 7th generation iPod nanos.
For up-to-date information, run silverutil -h:

Each section is transformed to a separate YAML file. An example of a such a representation is as follows, from the section StrT (named StrT.yaml):
magic: StrT
is_sequential: 1
resources:
- id: 1
contents: !String orientation.landscape
- id: 2
contents: !String orientation.alt
# [... continues ...]The special file metadata.yaml is used to preserve the order of sections.
Within the external rsrc ("iPod Resources") filesystem, UI translations and date/time locale can be found in SilverDB.xx_XX.LE.bin), along with bitmap images in SilverImagesDB.LE.bin.
There is an additional database internal to osos containing upwards of 40 sections, depending on the version. This contains the default en_US translation.
