Sorry to burst your bubble, but I doubt this will work. Each time you save, you're most likely to be saved on a different frame than you got in your last calibration. Also, even if you do save right when the NPCs stop, even if they don't move they may advance the frame still by making RNG calls to move. Mingot or Lightning Fusion or somebody correct me if I'm mistaken, but this probably won't work - unless you get lucky with your frames.Ok, after some stupid mistakes, I finally managed to breed the perfect Crobat (didn't play the last days, so it didn't take too long, really). Well, this shall be no spam/brag/whatever post, so I'm going to contribute a little, if it helps:
RNG abuse is great, but nevertheless, doing the frame calibration every time a new egg is to be fetched starts to really annoy me, as it takes way more time than hitting the delay for me. That's why I have come up with an idea that might allow us to skip the frame calibration for ever. I will test the method with my next breeding chain, but it would help to know whether my assumptions can be right beforehand. Here my planned frame abuse method:
Prerequisites:
- Prepare an egg with the desired PID and stand in front of the daycare man without taking it.
- Optional, but recommended: You should be good at hitting delays.
- and the usual stuff, of course
Step 1:
Now, carefully watch the movements of the people. Obviously, you can't stop Buneary, but you can easily hit the menu at a time, where the people will be standing still for a few time slices. Preferably, you should save instantly after they have made their last moves.
NPCs with fixed movement paths (like that Buneary) don't advance the frame
Step 2 (the step we wish to remove):
Do the frame calibration for the first few eggs (indepent from each other, which means, they are taken from different steps of a breeding chain or even different chains) you are getting.
The idea: Because we have kind of chosen what will happen next, the frame should be always low, like around 3. (I got 2 and 3 today, then I just went with 3 and succeeded hitting it together with the delay shortly afterwards). And if we get the said 3 (or something else, it's still related to the person pressing the buttons ;) ) every time, we can assume that it will be always around that 3 with the mentioned save method. This should allow us to skip the tedious frame calibration for further breeding projects. Who wouldn't mind that? ;)
Step 3:
Hit the delay, take the egg (=> coin test) and hatch it, as usual.
What if we got the wrong IVs having skipped the calibration?: Still check the IVs, so you can tell which frame you hit (=> adjacent results). If you were one frame off, try again. If you were a thousand miles away, you either saved at the wrong time or the method is nothing but a lazy wish. I hope for the former. Though, if the latter is the case, then just look for a different IV spread using the found frame.
So, I'll test it on my next breeding project if no objections are raised. I encourage anyone who reads this and also hates the frame calibration to try it as well.
All in all, it would take less time to just do your calibration again then hitting the wrong frame multiple times because you DIDN'T do calibration.
