I have a problem while trying to draw a sprite from a custom j2a file, a 800x600 png image. I am converting the image from a different palette to the JJ2's Palette. After I convert it and I save it in the specified format (0,-1,-1,0,0,0,0.png), j2a-import.py manages to import it in a .j2a file, but when I try to load from it, it gives me an Access Violation saying that the j2a is corrupt. The error is probably from how it is converted to the jj2 palette. I used GIMP to convert it to the jj2 palette.
