// of the Tinsel engine and graphics compression
|

// TINSEL_V1: There were two versions of the Discworld 1 game - the first used .GRA
|

// files, and the second used .SCN files. The second also provided some fixes to
|
|
// 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,
|
|
// and as far as we know there aren't any variations of this engine.

//
|
|
// 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.
