I remember someone saying it on a youtube comment,but i remember only the Posterize 10 part. Can anyone help?
(also i need help converting png to doom format)

For converting a png to doom format, go into slade then open your file, import the graphic, right click the graphic, go into the graphics subsection, then convert to doom format. If you don't have a palette set up or selected, it will appear grayscale.
