Protection PC, PC (Remastered) Saves are validated by a modified MD5 hash at the end of the save. It can be overcome using Bo98's save rehasher .
Other platforms No protection is present.
Row definitions Row definitions define the fields, or columns, used in each table. With different schema versions, new row definitions may be added and existing ones may be altered or removed.
Although row definitions are best read programmatically with the rest of the database, the structures they define are provided in a subpage for those who want to read them manually.
Structures Profile This is the overall savegame structure. Only the MUD database itself is defined in Criterion's debugging symbols; the rest is from independent research and prone to error.
