It is my understanding that in BW2 the first egg is always the same, however I've seen someone claim that their first egg will sometimes have a different gender. Why is that?
The fist egg is generated and stored in a call to the RNG that goes through a messed up process resulting in the egg returned being the same egg all the time. So, once you deposit the 2 pokemon and they lay an egg, that egg is set in stone. However, if you take it, hatch it, and keep collecting eggs, things work ... normally (actually, the process is still scewy, but aside from people who want to RNG the egg, no one will be able to tell or probably care). Now if you take the paents out of the day care and put in new paents, a few things might change depending on the gender ration, the pesence of a DW ability or not, the mothers ability, an everstone, and so on. But that first egg is set. If you collect it, hatch it, turn the game off and repeat, you will get the same result every single time. I'm still a little confused on the finer details of the egg generation process (can't RNG it, so there isn't much reason for me to go beyond that) but generally speaking, the first egg is the same until something changes or it is collected.
My best guess is they changed the parents around or changed some other factor.
It's still not working. I'm going to check I'm doing it right:
1) Go to location and save with a non-Synchronizer in the lead.
2) In RNGR, do what I've done in the pic in Time Finder.
3) Pick your seed, and go into the game, with the appropriate date and time, holding down the appropriate buttons until the game freak star appears. Then enter the game without turning on c-gear.
4) Without making the season name disappear early, sweet scent and catch the first pokemon that comes up.
5) Find that pokemon in the results generated on the main screen. That should be your initial frame. This is what mine looked like when I generated the results (let me know if it's wrong):
6) Set up the date/time again, and this time when you go into the game use, in my case, my two chatots to advance the frame.
Here's a question: the formula is (Target) - (Initial) - (Starting) + 1. Is my starting frame the frame Time Finder said (the one next to the seed column)?
7) Use sweet scent and bam, that should be the pokemon.
But it hasn't been. And can't figure out why. Thanks for the continual help, it is truly needed!
Okay, there are a few things going on here that could be improved upon to make this easier for you.
First and most glaringly, If you have an seed with an IV frame of 1, why are you not using that? If the Timer0 is the issue than I would narrow your Timer0 ranges and keep searching for a seed with IV frame 1. Just out oif curiosity, what are you RNGing and where? IIRC there are no NPCs around you yes?
Second, your method of finding your SSF is outdated and makes things harder on yourself. The main window will display Chatot pitches for each frame (Low, Mid-Low, Mid, Mid-High, High) and by matching these pitches you can tell if you hit your seed and where you are on your seed too. So if there are no NPcs in the area and you are using an IV frame of 1, the first chatot pitch should match what RNGR tells you your SSF is.
Third, you filled out Time Finder correctly and your seeds should work, but you shouldn't fill anything out in the main window as that will limit your results. just mark down the type of RNG you are doing (Gen 5 PIDNG in this case) and fill out other useful information, like synchronize, encounter type, etc, but leave the IVs, nature, encounter slot, ability, and gender blank. Those are more for gen 3 frame searching than gen 4/5 abuse.
Fourth, your equation is wrong ((Target) - (Initial) - (Starting) + 1) it should be Target Frame (TF) - Starting Frame (SF) - 1. So based on your screen shots Your TF is 314 and your SF is 55, so it should be 314 - 55 - 1 = 258 chatot flips. Do note though, if your IV frame is 4 and you are advancing your IV frame by walking in an area that spawns wild pokemon, you will be advancing your PID frame at the same time by 1 for every step you take. So if your SF is 55 and you advance your IV frame, your SF will be at least 55 + 128 (183 btw) but that number will vary based on the number of steps you take, NPCs, and other factors (using an IV frame of 1 is the easiest way to go as you don't have to worry about any of this).
Just a few helpful hints but other than that, you seem to have the right process down, now it is just a matter of persistence and luck
