[RM2K3] KNOW OF ANY TURN-BASED CBS TUTORIALS?

I've decided to make my game in 2k3 because it's most performant of the engines (and some of the stuff that I want to do would tank even VX Ace which is most performant "modern" RM) However, this leaves me in a tricky spot regarding battle system which is both buggy and not really what I want anyway (for example, I want to replace menu items with icons and no, EXFONT won't satisfy me on that one, another thing is that in RM2k3 there isn't really a way to customize battle formulas).

I can find plenty of tutorials on Zelda-like CBS, but I really want to do turn-based one. Do you know of any tutorials for turn-based CBS in 2k/2k3?
