Hey, I'm starting to use Advance Map. I already know the basics, like mapping, warp events, person events, etc but I need help with tileset/tileset palette editing. While I'm intent on replacing entire tilesets with my own work, I just want to replace a handful of 16x16 tiles in a tilemap without having the color mess up or not even have them show up properly.
Do you happen to know how much free space is in an average GBA rom, or more specifically, firered? I'm a little little bit concerned about space usable for the hacking of my rom, but it's just a curiosity really.
I opened up my sprite in GIMP and hand-typed in the color hex codes (I.e, 385d2f) from GIMP's palette list for my sprite in the color picker tool for each individual box in the changed palette. I then saved it as a .gpl file so I wouldn't have to do it by hand all over again. Yes, the palette changes fine initially and even looks fine if I reload the rom in APE after saving and go back to the palette offset.
1. Open FR Rom
2. Load "0046161C" Offset (Hex) for Red's intro sprite palette.
*with the "Compressed palette (LZ77)" tickbox unchecked.
3. Go to "Import" in "Changed Palette". (Index 1)
4. Import "Aiden.gpl"
5. Click "Replace".
6. Close APE.
