Set your DS time to one of the date/time combos listed in the Seed to Time dialog box for your target seed, taking off the seconds and however many minutes PikaTimer lists in the "minutes before target" field, which you can ignore as it's zero for this occasion, but you should know that for the future.
Ah, I see the problem - I think you just mistyped the seed. It's C80302F8, not C8030295.
Now, make sure you've got all the stuff entered into PikaTimer as I described before, then synch up your DS time, and start trying to hit your seed. Each time you enter the game, look up the Roamers' positions, and tell me what they say, and I'll tell you what to do.
