Would you mind explaining this a bit better? This might help me :)
Say I'm trying to catch Thundurus. I find that I have a seed at 18:44:49 with a Timer0 of C7F and a keypress of Left. After setting the time to 18:44 I go to the menu screen and wait. About a 10th of a second before 18:44:48 (so still at 18:44:47) I press A while holding left for my keypress. By pressing it a 10th of a second before the time I'd normally press it I get C7C for my Timer0. If for some reason I wanted C7E I'd press it a 10th of a second after 18:44:48.
Repost. Thanks.
If you mash, and I mean mash, A after you exit you can get consistent results. You should be able to find a relatively consistent increase in the PID after 1 or two advances. For some reason the difference between 0 and 1 advances is actually quite large but after that each PID you get should be either 1 or 2 after the last one.
