hello, sorry if my english is something bad.
to change the animations of the characters you must first move the .ema files to the emotool folder,
drag the files to show_anims_info.bat so you will know which animations to change is quite intuitive,
in the emotools folder you will find another folder
call mix_anims_examples
inside copy ATG_with_HLD_guard.bat and paste it in the emotools folder along with the .ema,
edit the .bat with the text editor.
now where it says set base = "ATG.ema" Change the ATG for the base of the mod.
where it says set other = "HLD.ema" you change it to the .ema where you will get the animations
in set result = "ATG_eternity_noshield.ema" you change the ATG_eternity_noshield for how you want the result to be saved.
now if you go down you will find this set animations_src = "HLD_GRD_KAMAE_A, HLD_GRD_KAMAE_B, HLD_GRD_KAMAE_C, HLD_GRD_L, HLD_GRD_H, HLD_GRD_FUTOBI, HLD_GRD_CLASH"
are the animations that of HLD that will replace those of
set animations_dst = "ATG_GRD_KAMAE_A, ATG_GRD_KAMAE_B, ATG_GRD_KAMAE_C, ATG_GRD_L, ATG_GRD_H, ATG_GRD_FUTOBI, ATG_GRD_CLASH"

once you finish modifying you just run the .bat like any application and the final result will be exported
keep in mind that they must have a similar animation time if it is less it will not Damage
