I also need help with this.
I need a ROM that lets me display a full-screen(160x144pixel) static image and can also be easily edited using YY-CHR.
Or advice on how to compile a GB ROM that can display a full-screen static image.
I want this so I can offer a better Custom/Modified ROM free service to everyone here -

Can anyone please help me out with this?
