Whew, after getting the starter over and over again, here's what I found. Hopefully, this will help others starting the game.
Pokemon White 2 (Retail Cart) - DS Lite
Timer0 Range: 10F3 - 10F5 (I am usually able to hit 10F5 closer to the actual second, 10F3 a little earlier, and 10F4 earliest. It doesn't always happen, but that's how I usually get the Timer0).
TID/SID Initial Frame: 37 (you might need to calibrate the initial frame, but regardless, it's not 28 like the default in Pandora's Box)
I am at a loss at how to figure out the initial frame for the PIDRNG for the starter. Hopefully, this info will help researchers:
MAC Address: 0019FD8ACF55
PIDRNG When Getting Starter Frame: 47 (I could tell because I got a Female Bashful Snivy)
