Thanks you for making this! Will you have a lesson on how to edit the continue screens in the future? I'm using an old mugen screen pack that's still using "Yes" or "No" continue commands. In IKEMEN it doesn't really display the same way it does in MUGEN. I really like the continue countdown from the default screen pack. I was wanting to add it manually some how. 
on Ikekem go its does have the display yes or no go to your system.def and find this command line
;Continue screen definition
[Continue Screen]
enabled = 1
legacymode.enabled = 1 <<< SET THIS TO 1 and you make into a Mugen Yes and no
;legacy continue screen (legacymode.enabled = 1)
pos = 160, 40
continue.text = "Continue?"
continue.font = 2,0,0
continue.scale = 1.0, 1.0
continue.offset = 0, 0
yes.text = "Yes"
yes.font = 2,0,0, 191,191,191
yes.scale = 1.0, 1.0
yes.offset = -17, 20
yes.active.text = "Yes"
yes.active.font = 2,0,0
yes.active.scale = 1.0, 1.0
yes.active.offset = -17, 20
no.text = "No"
no.font = 2,0,0, 191,191,191
no.scale = 1.0, 1.0
no.offset = 15, 20
no.active.text = "No"
no.active.font = 2,0,0
no.active.scale = 1.0, 1.0
no.active.offset = 15, 20
move.snd = 100, 0 ;Ikemen feature
done.snd = 100, 1 ;Ikemen feature
cancel.snd = 100, 2 ;Ikemen feature
