I'm not working on it right now. Busy writing a book
I'm actually helping with the FE4 Randomizer a bit, which Blyvern and friends are coding up. After it's complete, which might take a while, we'll move onto FE5, then look into the GBA randomizer to make my vision complete.
I also plan to, if this works, implement Crazy's skill system for even more crazy randomization possibilities!
