I'm trying to modify Portrait of Ruin's GFX for both Jonathan and Charlotte's info screen in the sprite editor, under Others -> Info Screen.
However, whenever I replace their Info portraits, DSVania crashes on me with the following crash log:
I tried this on both Linux and a Windows 7 machine with the same result.
For some reason it doesn't let me overwrite anything from that image.
In case it helps, this is the image I am trying to import using the "Import GFX" option:

It uses palette 02 from the Sprite Editor.
Also, I wanted to ask, do you happen to know what is the exact offset for those graphics?
I know the pointer is listed there, but having the exact offset where the graphics are stored in there could be helpful as well.
