however if you are playing tag ladder or a tag match,it allows you to play/use that specific mod,say for instance the swapped xrays,mind you swapped babalities dont need the other char,unless you want to hear the missing sfx for that babality.
also if a character like scorpion_b(alt.costume) which i modded,shao kahn doesnt need to be on the fight,if you perform the xray agaisnt another character,scorpion will freeze and be completely invulnerable against any attacks.
so yeah,this pack was more intended with tag ladder gameplay,not only that but brutalities,mercy,anti-fatality and auto fatalities can be done on 1p with no issues whatsoever.
in other words,save for the char_ files,you dont need another character to be on the fight to use the other parts of this modpack.
hope you have fun!
i want to mention,this same thing(swapping sfx and vo through scriptbinary) can be done on vs dc universe,and im sure it works better since every vo or sfx file is out,so you dont need the other char to eb on the fight,i still have to test it,but it looks like it will work better with mk8 than mk9.
