So I unearthed my old copy of this game during a recent Bullfrog nostalgia trip (Theme Hospital, Dunkeon Keeper and now this) and found some useful little tools around like PopRes. However, I have no idea how it works - apart from the obvious height and width values, it also requires a depth value, which has me stumped (not really literate in that field). I've been sticking in a value of 1, which doesn't seem to do any harm, but I'm also getting dodgy graphical glitches (scatty, inversed colours making unplayable landscapes) in-game that I can't seem to fix. Running compatibility mode for Win XP SP3, if that's any help. Anyone managed to get this game running at a decent res on Win7?
