Make a realistic 9x bootscreen

A lot of people don't do 9x stretching correctly. Here's how to do it correctly on Paint.NET, GIMP & Photoshop
== Paint.NET ==
# Create a bootscreen at 640x480. Make sure you have placed the loading bar, and it is stretched from 640x400 to 640x480.
# Resize it to 320x400 with bilinear resampling.
# Save it as a .png and set its bit depth to 8-bit.
# Open the .png and resize it again to 640x400, this time with nearest neighbour resampling.
# You should now have an authentic looking 9x bootscreen!
== Photoshop ==
# Create a bootscreen at 640x480. Its mode should be RGB. Make sure you have placed the loading bar, and it is stretched from 640x400 to 640x480.
# Resize it to 320x400 and add 256 color local indexing.
# Resize it again to 640x400 and set the color mode to RGB.
# You should now have an authentic looking 9x bootscreen!
== GIMP ==
# Create a new image with the size of 640x480.
# Make your screen.
# IMPORTANT! Merge down all of the layers.
# Go to Image > Scale Image.
# Scale the image to 320x400 and set the Interpolation setting to Linear.
# After that, Go to Image > Mode > Indexed.
# Set the colormap to 255, and the dithering type to Floyd-Steinberg (reduced color bleeding).
# Go to Image > Scale image… again.
# Scale the image to 640x400 and set the Interpolation field to None.
# After that, you’re done!
