Okay... you see the tileset for your character in RPG XP?
It is 4 by 4, being 4 rows of animations for the four movements, cool?
Well, Charas makes their stuff for an older version that simply reused and flipped bits and pieces of the template to EMULATE the four frames... Plus it's 3 x 3...
Idea for you to try out... grab the charas template okay? and then export one of the templates from the RPG XP, and match the poses. Sure you might have to flip some tiles around, and of course, doesn't hurt to go ahead, if you're using photoshop to edit them, to use the ruler and snapping grid to make sure your tiles are coming out right.
I believe the Charas pics are 92 x 112 and the RPG XP ones are 128 x 192 or something like that... I don't entirely remember...
