>how they determined all the off-screen battle stuff i.e. one of the officers on your side across the map reaches 50 KOs. the PS2 obviously wasn't strong enough to run the battles you can't see in real time so there has to have been something.
Off-screen processing is very different than what you see on-screen. Short answer is that what's going on is literally only stuff around you. As in, if you had bird's eye camera and could zoom out, the rest of the physical map would be completely empty. We have to look at the minimap then.
First off, each dot you see on the normal minimap(not the zoomed one) represents a group of 5 people or an officer with their bodyguards. They share a group HP value, you can see roughly how it works in this video:

Each army has either a fixed route and will fight whatever stands in their way, or have assigned targets to chase. These change whenever certain conditions are achieved(e.g. the target is defeated, switch to another target) or according to some battle events. Collision isn't the same either, the dots can phase through some obstacles and walls, just not map borders usually. Height doesn't exist either, so for instance infantry can fight against archers stationed on the towers/building off-screen.
As for how the fight works, when the dots glow yellow they are hitting each other. The damage and attack frequency depends on the difference in morale, and in DW3 also the player stats(if you want more info on that, same channel has
https://www.youtube.com/watch?v=IRWjH0lMs8U ). The army with lower morale always loses, always, no exceptions. They straight up cannot kill a higher morale unit, so it's only a matter of how fast they lose.
Boulders and terrain damage also exist off-screen.
