What type of system are you using? Are factoring in your seconds value when you boot the game? Its usually one second before the target time for most people
Oldest DS posiblle. My differential is +1. tried all sorts of time combos, but noone came out well. Will try different seed, and if that fails, a seed without keypresses. Yesterday i RNGed the 3 legends shiny near flawless and had as good as no problems hitting my seed. Also did a shiny scraggy, no problem. tried shiny axew later that day, again, couldn't hit my seed. And now again, can't hit my seed, did catch a flawless non shiny ditto without problems inbetween so ye.
Gonna try 2 more seeds, then one without keypresses, and see if i keep the same problem. If i do keep the same problem, im going to do everythung from scratch, posting everything i do step by step. But let's assume the other seeds do work, or atleast hope so hehe.
If i fix this, rest should be piece of cake, and then i'll try a shiny shelder, but one step at the time.
Ah that helps for verrifying, now lets try the other seeds.
Edit: Finally did it! I guess it was my timer0 not being able to go with that seed? I took a different seed, and hitted my seed on the first try, nicelly verified in route 13, hatched egg on frame 51
Edit2: Flawless corsola hatched! Your guide was awsome, and couldn't fix the problem without ya help, so yeah, 1000x thanks. Now will take it one step further and go for a shiny shellder using this corsola! :D
