Limited to the Windows Steam workflow whose build 17691957 reader ignores the trailing hash comparison. Builds that enforce that hash are outside this guide.

Editable values and their limits
Resources and upgradesChange existing Money, Caviar, HardCurrency, experience, level-index and upgrade values.
Boats and progressionEdit mapped health/cargo values, existing item quantities, quests, caught-unit flags and local unlock records.

Keep existing records and collection sizes. Large scientific values retain their original text representation; local Steam item flags do not change server inventory.

Notes

  • The trailing integrity footer is retained after an edit. This workflow is limited to the Windows Steam reader described above; it does not provide a new valid footer for other builds.
