I sense a disturbance in the Force ...
Aurebesh was based on the characters that appear in Return of the Jedi, but it was not created until the 1990s by West End Games for the Star Wars role playing game. When West End Games created Aurebesh, they were clearly trying to emulate the font seen in Return of the Jedi, but many characters are different.
Nowhere in ANH or ESB does that same font from ROTJ appear. They are all different alphabets.
I'd love to make a font based on Luke's X-Wing screens, but the text is blurry even in the HD captures.
