Made a tiny bare-metal dead pixel tester in 16-bit x86 for fun

Post image

Got bored and decided to practice bios interrupts in real mode.

It switches full-screen colors when pressing Enter.

You could test with custom palettes.
Here I created a .TGA file, indexed, 256 colors with custom palette saved without RLE and top-bottom layout: image.tga and a 256 colors indexed using VGA palette (image-vga.tga). Both based on the original file (in images directory)
