// various script bugs and coding errors, but is still considered TINSEL_V1,
// as both game versions work equally well with the newer code.
// TINSEL_V2: The Discworld 2 game used this updated version of the Tinsel 1 engine,

//
// You might wonder why is needed and here is the answer:
// The save/load dialog of the GMM operates with the physical
// savegame slots, while Tinsel internally uses entry numbers in
// a savelist (which is sorted latest to first). Now to allow
// proper loading of (especially Discworld2) saves we need to
// get a savelist entry number instead of the physical slot.
//
// There are different possible solutions:
//
// One way to fix this would be to pass the filename instead of
// the savelist entry number to RestoreGame, though it could make
// problems how DW2 handles CD switches. Normally DW2 would pass
// '-2' as slot when it changes CDs.
//
// Another way would be to convert all of Tinsel to use physical
// slot numbers instead of savelist entry numbers for loading.
// This would also allow '-2' as slot for CD changes without
// any major hackery.
