Interestingly, this could be circumvented - the boot rom does the logo scroll using data from cart, THEN, in a separate loop checks it vs local copy. If you can make the cart read different data at each stage, you are golden!

IIRC Argonaut/Jez San had a POC of this using a very simple hardware bodge, intended as a potential way of publishing Eclipse (What became X) without a Nintendo licence.

Fortunately - Nintendo were interested in the 3D rendering, and that started the SuperFX/Starfox/ARC journey.
