With perhaps ASM or a contraption?
I'd like to make a hack with one level that does one thing: changes the color of the screen (to something bright like red, green, yellow) when a face button is pressed, and reverts the color to blank (black would be suitable) when the button is released.
It would serve as a utility hack for easily measuring and adjusting input lag with a high speed camera.
Fancier options such as flashing the colors red for A, yellow for B, etc would be nice but not required.
I'd like to use the hack for a guide on how to precisely adjust input lag for emulators, as I'm tired of the myth that it cannot be matched to console. Such a utility hack would make it a bit easier for everyone.
Thanks!
