How do I change the character sprites to my own chars.

I used to use a very similar engine in rpg vx, but that came with a tutorial.

All I need is a simple tutorial on how to edit the Enu SBS Tanketai XP.

As far as I know there is such a tutorial on this site but I cant for the life of me find it

What do you mean by your own char? Do you mean your own graphic sprites? If that is so, just change your Characters Sprite in the database and the battle system will automatically 'adjust' itself. I'm currently using this battle system so I think I know it features very well.
