(I completely forgot about this topic)
Hi @Kliss88, yes, I finally managed to solve the problems listed above with the help of great people from the discord channel in fact if you use the Buildfile and you have any doubts or problems I suggest you ask them.
Returning to your question, to “extend” the palette limit you need Gamma’s ASM code
but be careful, it does not really expand the function of the base game that assigns the palettes, but creates a new one, in fact it assigns the palettes according to a combination by classes, and no longer by characters, so if you are using only FEbuilderGBA you will not be able to use it , you will still have to go through the Buildfile, or through MakeCustomSkillSystem (I don’t remember what that new FEbuilder function is called, I haven’t used it for three months)
anyway, the installation is quite easy and intuitive from Buildfile, the only thing you will have to go and fix is the .csv table because I believe it was taken from Sacred Echoes?
however, if you have problems, I suggest you to ask on Discord or to open a new topic, and not to brush up on old topics because otherwise you risk that people will not see your questions
