I'm still having a lot of trouble with the egg IVs. I found that I could save the game in front of the daycare man at a new time, then do all the steps to change the date to get the right seed for a perfect spread and I'd get at most two adjacents before I'd start getting "no Elm responses" over and over.
After two days of this, I decided to calibrate again just to see what was what when entering the game. I have discovered I get a consistent frame 3 when picking up the egg from the daycare man. I have a delay of 493 to 495 and my seconds are 15.
Someone told me frames don't matter on HGSS, but I'm seriously doubting this is true at this point.
Today, no matter what I do, I'm not getting Elm Responses. It's very discouraging. The first and only successful egg IVs I did on HG was a success after only two attempts to reset the clock. But this time, I feel like my game is cursed.
