Are there any chances that the PIDRNG starting frame for hidden grotto Pokémon could be off by 1 with certain seeds? I am using RNG Reporter 9.96.5, btw, which should be the latest public build.
I'm playing with an Italian Black 2, Memory Link has been activated. Here's any remotely relevant info I can think of...
ID: 46321
SID: 58677
3DS MAC: A4C0E100D4F6
VCount: AC
GxStat: 6
VFrame: 8
Timer0: 1667
The seed I correctly hit is 6DB24CFF8A85E6E0 (the IVs did confirm I properly hit the seed). Here's the standard seed info from the time finder:
Seed: 6DB24CFF8A85E6E0
Frame: 13
IVs: 31/31/31/2/31/31
HP: Electric 70
Date\Time: 11/01/12 19:03:01
Timer0: 1667
Keypresses: None
I do have both Black White 2 and Memory Link checked in the main RNG Reporter page. This gives me 53 as Starting Frame, and I wanted frame 104 for the Jolly nature. However, doing 51 Chatot advances brought me to a Rash nature, which is on frame 103 according to RNG Reporter. Tried a second time and it came out Rash again with 51 advances. The third time I tried 52 advances (which according to RNG Reported would have brought me to a Modest nature on frame 105), and I had the Jolly nature I wanted.
Now I'm not sure if I fail terribly hard with math/counting chatot flips, but as another hidden grotto seed I used went fine with what RNG Reporter told me, I thought I should probably inform about the fact, just to play it safe.
EDIT:
Pokécheck screenshot. The PID is the same one that RNG Reporter tells me for frame 104.
EDIT2: I forgot to say a possibly important thing: the hidden grotto seed/frame combo that worked correctly for me before was on a Ditto, which is obviously genderless, so that might have had a say, too.
