Making Default Spellcasters use Spontaneous Casting

[Legacy_jackkel dragon]

               So I found a few alternate spellcasting rules that I liked on the internet, which isn't hard because I dislike Vancian casting. I thought I might try to convert the system to NWN, and for the most part the system makes the default casters use spontaneous casting with sharply limited uses per day.

What I'm wondering is: how do you change the default spellcasting classes to use spontaneous casting?

               You would have to hack the exe or use extenders like NWNX because it's not possible in vanilla NWN.
