Self-damage revisited

[OldAmber]

I need 1 specific interpretation from your ruling:

It comes down to reading the cards.

If something adds to damage to "Active Pokemon", both Attacking and Defending are Active and so any damage done to either of them would be added to.

If something adds to damage done to the "Defending Pokemon", then only damage done to the Defending Pokemon is added to.

If something protects against or lowers damage done "from attacks", then damage from the Pokemon's own attack is protected against.

If something protects against or lowers damage done from "attacks by the opponent's Pokemon", then self damage is not protected against.

Look at the card and see if there is any source or target restrictions and apply them. If there is no restriction, or the restriction doesn't apply, then the effect is applied.

Given that ruling - and the text on Black Belt reading this way:

Black Belt -- "During this turn, each of your Active Pokémon's attacks does 40 more damage to your opponent's Active Pokémon (before applying Weakness and Resistance)."

As I interpret your answer, Black Belt meets your last criteria for "target restrictions" (to your OPPONENT'S Active Pokemon) so is to self-damage the exact same as not having the Black Belt at all: Zekrom and Regigigas EX takes 0 self-damage from the Black Belt. ONLY the opponent takes the only additional damage. Is this correct?

Right. Black Belt's effect is only applied to the "opponent's Active".
