Rare footage of a program that's useful for hacking but doesn't actually do much for FEXNA. Don't get used to it :R
Given a GBAFE rom, this program will display all of its tilesets with correct colors and, more usefully, provide their palettes with controls to edit them and see the changes immediately.
It doesn't actually write anything back to the rom, but you can save your completed palette as a bin file and import it manually (if you know how to do that, someone can probably explain it this would be a good place to link a tutorial if there is one???). You can also copy/paste a palette as an image, if you want to take it into a more robust image editor and globally adjust the brightness or hue or whatever.
The more potentially exciting bit is that I figured out the format of the tilesets ingame to put this together, which means theoretically in the near future you guys can have custom tilesets; the source code is included, which is good, because I'm not going to be the one writing said potential tileset editor, but you can use my code as a basis.
(oh I didn't before this moment realize it should probably be under a license if I'm letting people edit it? uh let's go with creative commons attribution 4.0, sure)
Special thanks to Nintenlord for the libraries used to read data from the roms.
(And then special unthanks for his dlls suddenly ceasing to work for a bit just after I uploaded this??? w/e fixed now)
