Hi, this savegame format thing has been getting on my nerves quite a bit. Last night I thought what the hell, I’ll get this done and just hacked together code to get forward (1, 2, 3). Recently I reverse engineered Operation Stealth’s PC version’s savegame loading routine and using that information I wrote documentation of the format to ScummVM’s wiki.
My idea why I wanted to reverse engineer and use the information from the Operation Stealth’s disassembly for the savegame handling is that if I know what the original engine thought was important enough to be saved to a savegame file I can use that information to save pertinent parts of the Cine engine too. So what was good enough for the original Operation Stealth engine should be good enough for the Cine engine as well.
A word of warning about the savegames: The savegames for Operation Stealth are going to be very much a work in progress and therefore backward compatibility can be broken at practically any time and the changing formats will not be supported later. They are only a tool for development. A bit later it’d be very nice to share resources with the SCUMM & Tinsel engines so the three engines could use the same code for handling their savegames.
