I've expanded all the tables. I've not started move effects, or animations. I'm working on move descriptions and ability descriptions at the moment. Once those are done, I'll start doing move effects and ability ASM.
The Fairy-type expansion is perfect, except that it doesn't work 100% with Tlachtli's PSS Icons. Once I work out how to fix that bug, i'll write up the tutorial.
In the mean time I can give you the offsets of things. You should be able to work it out from there.
