Combining the saving and loading into a same function is simple brilliance. Very nice. I'll go drink myself happy now :-), going to do some coding on Sunday next.

As Operation Stealth is WIP I'll probably just modify its savegame format along the way if I need to, but I'd really love to use a shared savegame format serializer/deserializer, I'm all for it!

We were considering switching to a chunked system at some point, too, but then came up with this approach instead, which is very flexible, was easy to implement (little changes required compared to the original system), and also incurred almost now size overhead in the savegames. We replicate some of the code in the Tinsel engine now (in a revised/improved variant, but still without the cool versioning feature), and my plan is to make that code fully "versioning-enabled", too. If you are interested, we could try to make the code flexible enough to be shared by Cine, Tinsel & SCUMM and put it into SCUMM. Indeed, check out the SCUMM savegame system.
