Castlevania Harmony of Despair - How to do Tackle glitch without lag

[@ulrikr83]

How do you do the tackle when you are in the help and options meny?

I do the tackle when the mp below 15. The game programs the command when the mp is not enough, when the mp is 15, it will do it. Then I quickly press start+option to get full lag
