Something just keeps bothering me and I'm dying to know.
The other day when I was trying to RNG capture a wild kangaskhan on my Soulsilver, I was able to hit my target delay by starting out with 1 starting frame but I didn't have my tropius with sweet scent. So I went back to the pokecenter and to get my tropius, then I went back to the cave, saved my game, turned off my game, and try hitting my target delay again. After I managed to hit my target delay again, somehow I managed to start out with two starting frames instead of one. (I found out after looking the elm calls)
The question is how did that happened? First, I start out with one starting frame, and then suddenly, it just start with two starting frames.
