Reference

This editor uses the documented SYSCONF layout: SCv0 header, big-endian values, item offset table, typed records, lookup table near 0x3FAE, and SCed EOF marker. It edits records in place and does not add or remove SYSCONF items.

Fresh or partially configured NANDs may legitimately be missing later-created settings. Some homebrew also leaves the lookup table empty; Wii software can still find entries by scanning the item table.

For BIGARRAY and SMALLARRAY structured editors, the array length prefix is parsed and preserved, but the visible fields are payload-relative. This matches the homebrew CONF_Get and SYSCONF_Get behavior.
