Text animation Snes and Steam version?

which reminds me... anyone has any information on how to tweak expand dialogue code? special characters in particular

$12, $17, $18 might be free, check in bank $C0. Just follow the code in DTE routine when it check if byte < $20. After this the code check if it is an actor name ($00-$0F) then it's a bunch of if / else for remaining possibilities. There is some dummy code in the region where the last if / else is, you can put you condition for a unused byte and new code there. This is what I did for my text centering special character. I think I used $18 but I don't remember exactly.
