; The characters in the FDS font are 1 bpp, not 2 bpp as you might expect.
; Each byte of the character is copied twice to fill out the two bitplanes in
; CHR-RAM.

; If you kinda squint, you can see the characters in the 1s and 0s below, since
; it's in binary. The hex representation of this data is not useful.
