Oh I see what your doing. I don't have the patience to put that counter on 60 but thats not relevant here. By making that count to 58 instead of 60 you would not have need to adjust your target time, but considering you have changed your target time leave it at 60.
Your Target time is 18:10:28, when hitting close to your delay, how far away the second your hitting? If you get 18:10:27 change your other counter to 61, on the other hand if your hitting 18:10:29 make the other one 59.
Set your DS clock to 18:09:00 and as soon as you hit 'set time' hit space bar to activate your emloop. Boot up your game and when the 1st counter reaches 0 Soft Reset (Start+Select+L+R) Once your on the continue screen wait for the 2nd timer to reach 0 then start the game. If thee are no NPCs in your area do your coin flips, if they do not match, catch a poke and find what you hit so you know what to adjust.
Sorry if I've repeated alot of what you already know I just want to be thorough. And the last part of my last post was regarding HG/SS frame advancement which i was discussing in another earlier post of mine.
