Right click your King's Bounty game in your steam library, Properties, Set Launch Options and type "-dev" without quotes of course. This starts the game in dev mode not just from a short cut.

I wouldn't have believed this topic was still active after so many years !
Now maybe it would be a good idea to have some kind of central repository for the fixes which can still be useful, like github although these kfs files would not be very convenient for git, but it's worth trying to setup something, most links in these pages are dead now, only the code directly displayed or the attached files are still usable...

And that's why we attached them ;-)

Maybe some links can be accessed using webarchive. Also, are the bugs shown here in Ice and Fire too?
