Predicting espeon's iv early

Post by punyuta » Fri Mar 04, 2016 2:59 pm

Hi, I'm punyuta. Japanese speedrunner!
I think English community don't use any program to predict espeon's iv.
So I made a video that demonstrates how Japanese speedrunners predict espeon's iv by using program called xdseed and xdpokemon.
Video Link:http://www.twitch.tv/punyuta/v/52080178
Tools Link:http://www.geocities.jp/ginzaru_xd/

Tools are in Japanese and also my English is not that good. so I think it is difficult to understand but I think you will get general idea by watching my video.

If you have any question about this, feel free to ask me on this forum.
I hope this information would help you guys!

Thanks for posting this. The possibility with xdseed and xdpokemon to *maybe* actually manipulate the stats is fun to think about, even if it's not practical for speedruns in the end.

It was because of your tweet about being able to predict Croc's IVs that gifvex started investigating the Colo RNG, and between him and myself we were able to come up with a prediction method that is actually mostly different to the Japanese speedrunners method. Our prediction method is mainly based on the fact that we know that the trainer ID is generated a fixed number of frames before the game starts trying to generate Umbreon and Espeon. Also, the RNG can only have 65536 (2^16) values when the Trainer ID is made, since the upper 16 bits must be equal to the Trainer ID itself. We use these facts to quickly brute force search through all of the possible values to find the Espeon stats you enter, as the chances of 2 of the same Level 25 Espeon existing out of 65536 sets of RNG are actually really low.

I will post the English prediction program publicly soon once it has undergone a bit more testing in runs, for now if anyone wants it they can contact me directly.

I've used the program in runs for about 2 weeks, and it's worked really well for both Espeon and Croc prediction.

I'm glad if this information helped you!

Also, do you think it is possible to predict pokemon lab puzzle with TID?
(for example, BW2 plasma frigate password can be predicted by TID:https://twitter.com/search?q=punyuta%20mod&src=typd )
