Discussion about Heroes I.

Is there anywhere a description of the fastest possible completion of the initial 18 scenarios, such as Dragon Pass, Hemet Isle, Badlands, etc.? It would be interesting to compare it with my own results and see how many points I missed. I couldn't complete Dragon Pass on expert difficulty in under 10 days, but I'm sure someone has done it faster. I found information about this scenario in a great reference guide. Unfortunately, there are no working Heroes of Might and Magic I versions for Windows XP. Does anyone know what the trick is, how can it be completed in 2 days? And what was used to defeat the dragons?
