just wait, really. keep trying. for some it seems timer0 fluctuates based upon keypress and for others it seems to fluctuate on its own. it seems to be based on the firmware on your DS. i think i see a trend, but i'd like more data before jumping to any conclusions. you calibrated with no keypresses, right? if so, the times you missed your seed were likely when timer0 was hitting C81. that's interesting, thank you.
