i just figured that the different players' colors were all kept in the Cursor_CursorNumber.bflan. when you play the animation in Switch Toolbox (at least for me), it plays as colored squares over the player cursor. i'm largely just speculating, but maybe those determine player colors over CursorBaseAlpha?You can edit the base color of the cursor (the white hand) in cursor.bflyt by changing the background color of CursorBase. Changing the outline per player though has alluded me. Not sure where those values are, though I believe I may have just now discovered another valued that had been alluding me as well. Quite possible some updates to old themes could be dropping soon.
since the cursors i'm wanting to have are all black, i could just set each keyframe value (for CursorBaseAlpha) to 0, and Switch Toolbox shows everything right, so i haven't done too much with it. i figure it's saved as RGB values of some sort though
my main question regards -- i've changed the direct files for the cursor. all the *.bflim files, and it's not showing up in the finished theme when i export everything to Men.pack and install to my wii U (it only shows the color edit from your White Dark Theme). i didn't know if you could help me with that, if you knew anything about it? but if not, that's cool too, i'll just have to experiment some more with it haha
