I have some realistic-looking KML+BMP files for the HP-48GX, as documented
here.
I took "Wombat 3" VGA .bmp and carefully put "Jemak's GX" graphics from the desktop version of the emulator in spots where the Wombat 3 .kml file is telling the emulator to find the buttons. Then, I went through every single button and tweaked for readability, pixel-by-pixel. This took a lot of time! Please enjoy.
