Well it's not hard to find a seed... Use this to find a spread, take the seed value given and put it into RNG reporter's Researcher tool as the seed, select LCRNG [R], display as many frames you want to advance, and output it. Open the text file, search for 0000 under 16 bit high, and enter the corresponding 16 bit low value into your tool as the seed. Still that is fairly time-consuming but not that difficult.
However it's far more time-consuming to wait for the minute that the RTC will give the seed you want, especially if you end up not hitting your frame. Then what? You have to wait another ridiculous amount of time for the next seed (although some seeds are repeated fairly quickly but that's not to really be relied on). This just seems to be an exercise in frustration waiting to happen. Although I suppose this would make R/S abuse w/ the RTC really easy.
I'm going to try to leave the battery disconnected overnight to see what happens.
