@thomasorus a hex editor, is a way of looking at the binary(bytes really) content of a file. For example, each sprite, or sound, in Uxn is a series of 0s and 1s that turn into little drawings or waveform.
Think of this as a way, an ascii text file is a bunch of numbers from 0 to 255(https://wiki.xxiivv.com/site/ascii.html), a hex editor is a way of seeing these numbers behind the characters.
@thomasorus For example, if I open a text file, and I select some letters, here's what these letters correspond in bytes.
If I select the letter "i" in my textfile, it displays as #69 which is its ascii value.
