go to data, mugen.cfg (same method as Update 1) but rename data/ClimaxSacrifice/f to data/ClimaxSacrifice/f then save. ( UPDATE 2 ) - this screenpack contains 51 slots (default) 210 (big) 660 (exbig) if you're wonder how to choose or change the slots size that you want it's very simple to do. once you change this line motif = data/mugen1/f / just rename it like this motif = data/ClimaxSacrifice/f. ( UPDATE ) - In case some of you are confused that there's 2 files it's because the mugen 1.1 beta is the main mugen you're going to need to make this screenpack to work so the other one called MUGEN The Climax Sacrifice Motif.rar goes to the data folder of mugen 1.1 beta unzip it and change the mugen.cfg in the data not in ClimaxSacrifice folder but in the normal one that appears in the data down below. also make sure to read the 'read me' in MUGEN The Climax Sacrifice Motif.rar. I'm adding a default mugen 1.1 latest beta so you can install this screenpack yourself.

this is the screenpack i always used for my mugen. Literally the best screenpack for 1.1 I've found.
