Final Fantasy 7 style Limit skills

[apoclaydon]

Hi all I've been working on a RPG that uses Yanfly's Engine Melody as a base. What I am now looking for is a script that will allo me to set up certain skills to be limit breaks like in FF7 (when the actor is attacked a bar is filled and once full attack changes to Limit and grants the use of the limit skill). I have found a script that can do this but does not appear to be compatable any help would be great thank you
