I'm back, and like I predicted, I failed.
I was a bit confused with the ordeal, so I used the tutorial here:
http://youtu.be/oazP3bFPH8M
What I did was I saved atop Mt. Silver, then soft reset as SOON as the clock rolled over the minute. I got the following:
Seconds Delay
14 501
20 487
14 493
14 488
Then, I went to the 4th Gen time finder, chose Method K, Wild Pokemon, Any.
I entered:
Year: 2012
Min Delay: 487
Max Delay: 501
Min/Max Frame: 1
And chose defensive IV's. I chose a result which did NOT require me to use a specific lead, with 1 frame, 1 hour, encounter slot 5.
Then, I input it into the Seed to Times finder, chose HGSS and chose the first result:
2012 04 27
01:57:59
Delay: 492
Now, the guide said to subtract my 'seconds' from the time, which I did, and got 01:57:45.
I saved in a patch of grass, and soft reset exactly when the timer went to 45 seconds, then mashed 'A' like crazy till I got in.
Now, I've done this several times, each time checking my 3 roamers, and NONE of their combinations EVER show up when I press "Search Roamers".
I don't know what I'm doing wrong, but then again I'm new to this. Any help is appreciated. Thanks.
