I totally agree - Discord is the way to go. For those reading this thread I may have two reasons why Paras won't appear:

It could be IGT0 (in-game time 0): The save before the manip determines which result you will get. Pokemon Red runs at approx. 60 fps, so you've got 60 possible frames to save on. Some - typically 1 to 5 frames, depending on the manip - are considered "bad frames". If you save on one of those the RNG manip will not work. In this case something different will happen (like not getting an encounter, getting the wrong encounter, getting a bad early encounter or yoloball not working). Manips sadly are not perfect (the Inside Mt Moon manip I know has a 55/60 chance to give the desired Paras and a 54/55 chance for yoloball), but they are really good considering their high chances to succeed.

Another thing could be textboxes from items: You have to hold A until the jingle starts playing; this caused some problems for me, too.

Settings -> Input. Then just click in the top right hand box and register the desired keys on your controller by pushing them.

I also started running Red a month ago and totally agree - good savestates for the hard parts of manips save a lot of practice time, especially on yoloballing Nido and Paras. Also, don't get discouraged if manips fail - saving on bad frames (IGT0's) just happens, but it's quite rare. Keep on and you'll get your good times!

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

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

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!

I use LiveSplit and it works fine!
