Okay, so. I'm trying to catch a shiny, physical-perfect Growlithe on my copy of Black 2 (official, not a flash cart). I can hit my needed seed okay when my timer0's not trolling me. I seem to be having a lot of trouble with the PIDRNG advancement, though.
After a few resets, I figured out that the NPCs in the area seemed to advance the frame to 80 before I could actually access the menu, and from there I figured how many Chatot chirps I needed. But when I flipped the needed number of times, I wound up three frames over. I tried again with three less flips... and I wound up two frames under. I tried one less flip than I initially figured... two frames over. Two less flips... somehow five frames over.
This is starting to drive me up a wall, here. Is this wholly the fault of the NPCs/my not hammering X fast enough, or is there some other possible cause here?
Additional info if that helps:
Version: 9.965 Beta
DS Lite, MAC address 001EA9DF0085
Seed: 8A9FA0A4A418B18C (target PIDRNG frame 239, leading with female Cute Charm Minccino)
I don't know if I should include additional info like my IDs, but if that helps, I'll reply with them.
In addition... I don't know if it's just me being untrained in listening to these chirps, but so far, I'm finding I can't rely on their pitches to tell me what frame I'm on. They never seem to match up to what RNG Reporter says.
