I’m not sure about normal hacking and Tactile, but i know for a fact Lex Talionis, which is in my opinion the best of the three softwares to do Fire Emblem Fangames, does not have the limited hackbox where the edges get cut off, AND does not have the 16 color limit, while also being extremely customisable if you know Python.
Klok made a great comparison post between the three. Keep in mind the post is half a year old at this point, and LT is getting updated on the daily, so there are many more features than listed there.
And if you’re interested in Lex Talionis here is a link to the LT Discord Server
