Tip for those using Heroecopalka for Heroes 3:
The program's speed directly depends on the number of save files in the "..\Games" folder of Heroes 3.
This isn't very noticeable with a small number of saves, but when there are 200-300...
To solve this, you can temporarily move all unnecessary saves to another folder.
This is not related to the operation of "Heroecopalka," but to the operation of the game itself, specifically, the number of files in the Games directory affects the speed of reading files, and this is what causes the "extraction" process to be slower. The "Heroecopalka" itself is not the problem here.
Try to verify this empirically. Launch Heroes, click on single player, load. The difference in loading time for saved files with different quantities is quite noticeable. What do you expect, a computer is also just a machine...;)
