For the ID\SID abuse, you're going to use emloop.
Put your target delay in the red box, then click the blue box to get it in minutes and seconds. You'll notice your target delay (5600) comes out to 1 minute, 33 seconds. We want the DS clock to be 22:11:00 when we finish, so we're going to do two things to make sure. 1) Have the total time (yellow + green boxes) be two minutes, rounded down, so put 27 seconds in the green box. 2) Change the DS clock to 22:09 at the same moment you start the timer (click pink box).
Start the game at the exact moment the first timer counts down to 0. Make a new game, and press A at "I'll see you later!" when the second timer counts down to 0.
Now, there's a time gap between the time you start the second timer and the time delay starts counting. We will have to account for this gap. So the first game you make will only be used to calibrate. Plug in the ID you got into the Pandora's Box Seed Finder, along with the target date\time. It will tell you how many seconds and delay you are off. Use minimum delay 4500 and maximum delay your target (in this case 5600).
Pick a target ID in the search result that seems reasonable (like one that says 2 to 10 seconds). Calculate the difference between that ID's delay and your target, and adjust for this in emloop. For example, if you see an ID at 8 seconds with 5367 delay, add 233 to the red box (=5600-5367) and subtract 12 from the green box (=8 second gap + 4 extra seconds added by 233 delay). Now you've accounted for the difference, keep trying until you get the right ID.
It's always good to keep checking the IDs you get in the Seed Finder to see if you need to make more slight adjustments to your timing.
