Unused Configuration-Related Screen?

At $6BA8 is code that shows a screen that says "OPENNING_DAYO" and "A PULS START DE CONFIGURATION MODE DA". The screen fully works, but isn't used (or accessed, apparently). On this screen, pressing Start exits the screen and pressing A+Start enters Configuration Mode. In Configuration Mode, choosing Exit brings you back to this screen.

To force yourself into the screen, first use code 000BBC:4E75 to bypass the checksum, then use codes 00028E:4EB8 and 000290:6BA8 to change the jump into Configuration Mode into a jump into this new screen. Then, just enter Configuration Mode as you usually would (A+Start on the title screen).
