* The current savegame format version.
|
|
* Our save/load system uses an elaborate scheme to allow us to modify the
|
|
* savegame while keeping full backward compatibility, in the sense that newer
|
|
* ScummVM versions always are able to load old savegames.
|
|
* In order to achieve that, we store a version in the savegame files, and whenever
|
|
* the savegame layout is modified, the version is incremented.
|
|
*
|
|
* This roughly works by marking each savegame entry with a range of versions
|
|
* for which it is valid; the save/load code iterates over all entries, but
|
|
* only saves/loads those which are valid for the version of the savegame
|
|
* which is being loaded/saved currently.
