The SNES supports interlacing. It is available only in Mode 5 and Mode 6. [3] It is enabled by setting bit 0 of SETINI.
In interlacing on the SNES, the first field is called "odd" and the second field is called "even."
For even fields, the electron beam begins scanning at the top-middle of the screen instead of the top-left like in odd fields. For odd fields, it finishes scanning at the middle-bottom instead of the bottom-right like in even fields. [2]
