For a more technical explanation: Ace (and VX) reads sprite sheets without an $ in front of their name as two lines of four animation sets. If they aren't the default set (that is, if you've made custom sprites) just take a normal sprite sheet from the Mack set (like the above shown - 4 columns and 2 rows of characters), delete one of the characters and paste your one in. :sigh: The Mack sprite sheets should just work if you add them to your sprite folder.
