and just in case the tutorials weren't specific enough, you have to copy the name of the life bars then edit the system file in note pad and scroll to where it says 'Files" then paste the name of the file to where it says fight which should be right under "select", here's my system text configs as an example.
;----------------------------
[Files]
spr = system.sff ;Filename of sprite data
snd = system.snd ;Filename of sound data
logo.storyboard = loading.def ;Logo storyboard definition (optional)
intro.storyboard = intro.def ;Intro storyboard definition (optional)
select = select.def ;Character and stage selection list
fight = Blue VF5 Lifebar/fight.def ;Fight definition filename
font1 = f-4x6.def ;System fonts
font2 = titf3.fnt
font3 = UMMCtitle.fnt
font4 = titf1.fnt
font5 = titf2.fnt
font6 = UMMCitem1.fnt
font7 = UMMCitem2.fnt
font8 = font/UMMCtitle.fnt
;----------------------------
once you add you life bar save and exit, then see if it work's in the game, i hope this helps.
