Outpost 2 Saved Game File Format -------------------------------- Note: Saved games share much of the same loading code as the .map file format. They consist of a prefix to the .map format and (possibly) some data near the end. Note: Brett 24JUN17 The name of the saved game starts at offset 0x25. Max size of the name is 31 characters. Outpost 2 .op2 File Format (Saved Games) ---------------------------------------- Offset Size Description ------ ---- ----------- 0x0 0x19 "OUTPOST 2.00 SAVED GAME", 0x1A, 0 - String must match exactly or else load error --------------------------- 0x19 0x1086C fileDialogData 0x10885 0xD7A0 sheetData[0x73] (array of 0x73 (115) UnitTypeInfo objects, each loading 0x1E0 bytes of data) Note: Technically each object loads data through a virtual function call, so each object could load a different amount of data. However, there are no overrides, so they all call the same base class function, and hence all load the same data. 4 int requiredTechNum 0x1DC struct[] unitTypeInfo.playerInfo[] --------------------------- 0x1E025 ...
