hows the rtc, does it still have the small problem found in the m3?
in my m3 starting a new game of pokemon would reset the clock..
for example, if you played ruby for 2 or 3 days, and started a new game on emerald, ruby would prompt the battery message or clock would be wrong..
you could also notice this by, setting the clock on boktai, start a new game in pokemon and boktai would get back to default date in the 2000 year
it was kinda hard to "syncronize" the pokemon games clocks so they would match the same hour and aproximate minutes..
