Hello, friends! I'm working on improving the quality of the original H5 interface. I have a question about the hero's inventory. I want to improve the quality of the tabs on the left (army, inventory, abilities) and the quality of the spellbook icon. I increased the resolution by a factor of two and noted the new size in the xdb file. But as a result, this led to incorrect display, much larger than the actual size in the interface. Is there another file that controls this? Why does this practice work in the game creation menu (player flags, cities, heroes, bonuses, dice), but it didn't work here?
