Other than the fact that setting the clock in RSE (and also Jambo's custom day-of-the-week setting routine) is no no longer supported, I like this tool. At least the clock is displayed correctly. If you could just add in support for these two things, I would be grateful.
In other news, I seem to not be able to remove the old RTC/DN system from my FireRed ROM. It gives me an unhandled exception and quits.
