Oh wow. Thank you so much for this. Maybe I’ll be able to finish this brilliant thing now.

Some clever types recently made a variant of this mod to make a widescreen mod for the Dark Engine games. Thief 1 2 and System Shock 2. No clue how they managed to get an Infinity engine mod working with Dark engine, but I’m happy they did.

The history of Widescreen for the IE is that weak-ling (the same dude that made the System Shock 2 hack you link to) originally made an hack for Baldur’s Gate II at 1440×900 (by simply overwriting the relevant files). I spotted it and wrote a mod around it so that it asks the desired resolution (and, with help from both weak-ling and Avenger, also expanded it to the other IE games). Since my mod used a full, six years mature uninstall framework and had highly generic code for this type of patching (it declares a list of offset-oldvalue-newvalue triplets and tries to apply all of them, with support for different lists for different game versions), Weak-ling adapted it to the Dark Engine rather than write a patcher from scratch (usually, game cracks and similar have a similar VC framework in which you have to plug your offset-oldvalue-newvalue, but it doesn’t contain support for actually asking your resolution).

But still, good work. it works like a charm.
