Could someone please give some tips on how to abuse your ID on Diamond. I'm using an orginal cartridge if that helps.
The first thing you need to do is calibrate - for this, I recommend synching your DS up to an external clock, then trying to get through a new game and cancel the TV screen (that's when your ID/SID is generated in DPPt) for a particualr time - when I was calibrating on Platinum, I tried to get through in exactly two minutes - I would reset at the top of a minute, then rush through the new game sequence and sit at the TV screen for 10 seconds or so, then pressed A when the second minute passed. Then you just note down your delays, until you can consistently hit a specific range
If you're using PikaTimer, then, assuming you use the two-minute calibration method, put in your calibrated and wanted delay, along with your calibrated second, then make your wanted second the same as your calibrated one (use RNG Reporter to find a suitable time for this second), then, take the second timer, and manually add 120 seconds to it. So if it says 11.3 seconds, change it to 131.3 seconds. Leave the first timer unchanged.
Past this, just follow the guides on the front page of this thread.
