So, if that's the case, why bother with generating convenient starting save files or fixing the issue of morale dropping for 3 stacks in a row, making it impossible to win a battle – because the desired event will happen sooner or later anyway? Let's just create the desired scenario directly in some plugin.
I once saw screenshots of a Chinese player completing a map without the HD mod. He left a hero without an army, giving him the maximum speed boost, so he could reach the required point in time. For me, this is not acceptable, but someone might think otherwise. For example, speedruns of various games are done using all the bugs of the original game.
Yes, it won't be possible without the HD mod and SoD_SP.
