Thanks for the explanations. If I understand correctly, you have the
same problems SCUMM (and, I'd guess, most other engines we support)
have. In SCUMM, we solve this by delaying loading and saving. I.e.
when asked to save/load, we don't actually save/load, but rather set
an internal flag that a save or load should be performed. Then, in the
main run loop, we check that flag in a safe spot. In fact *all*
loading is done in exactly this manner, ensuring uniform handling.
Of course, this might lead to unexpected behavior if the next time the
"safe" spot in the main loop is hit is after a major event, say only
after the completion of a cutscene or after a room transition. So one
has to take care to disable loading and/or saving completely in the
GMM during these times, so the user can't trigger these at all.
Would something like that work for you?
