EDIT: I found out after endless attempts that it is in fact NOT an IGT0. Both things PinkishPrincess said down below caused enough frames to pass to consistently give me the encounter. Holding A directly after resetting and to hold A on item pickup until the jingle plays did the job! Thanks again for the help!

Hey guys!

It's rather embarrasing to ask: Way too often I get a bad early encounter on Full Moon manip. It's a Zubat Lv. 11 right behind the sign left to the Lass. I'm guessing it's IGT0 because re-saving does the trick, but I just want to make sure...Could it be bad execution or another thing beforehand which messes with RNG?

Here is the video:

Thanks a lot!

2 things:

1. You want to hold A while resetting instead of when the white screen appears in intro.
2. Hold A while the textbox is printing for picking up items.

With both of those being said, yes. That is IGT0.

Thanks for the tips, I'll keep them in mind!

So I'm just unlucky - oh well. :P
