I've added all 20 missions and all 6 difficulties for both characters in the Individual Levels section. Rules: Everything goes except super costumes and items. This means you can have maxed out HP/DT/Styles/Devil Arms/Guns. The timing method is IGT given at the end of each mission. Submissions require video and must show the difficulty select menu (before or after attempt) and result screen IGT.

Addendum: difficulty select menu can be shown either before or after the attempt. This means you can restart the mission faster by choosing restart mission instead of quit.
