Nice buddy. how to use Palette Converter. I tried but do not know how to use it.
1. Click "Add new transform".
2. Change blocksize from 16 to 256.
3. Click the first row (gray) in the left box.
4. Click the first row in the middle (empty) box.
5. Change blocksize back to 16.
6. Change rows in the middle box as desired. To do so, click on a row on the left box and then on a row in the middle box.
7. Click "Save changes".
8. Load a file by dragging it into the working area.
9. Select your changed palette from the dropdown. The new palette is called "transform_NEW", unless you named it differently.
10. Click "Convert".
11. Click "Download".
