RNG Research

[RotatingAtom]

Is playing an english (UK) White 2 Version on a german DSi a special case you guys need data for? Or is it just the version language that matters for RNG purposes?
Also, is RNG'ing (including the calibration process, finding your parameters and such) significantly easier on a DS Lite than on a DSi? Or is there no difference?

It's language specific so you're fine. I'm actually shocked that it works on the German DSi for you. The DS Lite is slightly easier because you can set the clock with the A button instead of being forced to use the touch screen and it has a second hand on the main menu. Really though it's a very minor difference and you should be fine with either.

I couldn´t capture a Chatot, so I saved the game ONE time in order to advance ONE frame the PIDRNG. I assumed that save the game is the same in BW2 that in BW. If it´s wrong, tell me and I will make another test the weekend, including Black 2 results.

[Slashmolder]

Saving still advances the PIDRNG so that works fine. Thanks, I'll try to get Reporter updated for Spanish games ASAP, probably waiting on the Black 2 results.

the egg seed bug in bw2 also applies to ivs, so the ivs will be set for the first egg. they make, no joke, 18 ivs for a given egg and only use the middle 6. this is very depressing. they really drive me crazy sometimes.

I just got Korean White 2, which was released yesterday. I have only it and Korean/Japanese DSL. Can I help anything with them?

Unfortunately the only way to obtain the data we need is to do the process on a DSi or 3DS. Thanks for offering.

Move Recommender in Humilau



rand(5) for the recommended move. Simple.

Hey, Trainer! The move I recommend for you is none other than Roost! Roost is a move that can restore HP! Also, if a Flying-type Pokémon uses it, it won't be Flying type during the turn, which means the type matchup will change. A supereffective move will be an ordinary move, or a move that would otherwise have no effect will land on it. It's a quite tricky move.
Hey, Trainer! The move I recommend for you is none other than Synthesis! Synthesis is a move that can restore HP! When the sunlight is harsh, the Pokémon can restore a lot of HP. But in rain, hail, or a sandstorm, the Pokémon cannot restore HP very much. So, watch out for the weather!
Hey, Trainer! The move I recommend for you is none other than Heal Bell! Heal Bell can heal status conditions of allies. It's a loving move to heal status conditions of all the party Pokémon!
Hey, Trainer! The move I recommend for you is none other than Tailwind! Tailwind doubles the Speed of all party Pokémon the turn the move is used and for the next three turns. If Pokémon can act before their opponents, they can have an upper hand!
Hey, Trainer! The move I recommend for you is none other than Pain Split! Pain Split adds the user's HP to the target's HP, divides it by two, and has the Pokémon share it. Use it when the target's HP is higher than your Pokémon's HP. You can reduce the opponent's HP while recovering your Pokémon's HP.

Was just a test so I could see how the game gets random stuff by just using scripts. The game uses script command 00CB to get a random number with a certain max value (in this case, 5) and then displays an entry of text corresponding to the resultant random number. Slash and I were discussing other ways to calibrate besides catching... the TV is much more 'random' so that'd probably be a better route. That's for later :)

What's the process? I've got a DSi, I'd like to help. Sorry if I missed it, only read Mingot's first post.

Alright, met with a few friends over the weekend and one of them had an Italian White 2.

Game: Italian White 2
Console: Italian 3DS
Mac Address: 58BDA32F0D0F
Date Started: December 11th, 2011
Time Started: 10:15:25 (actual second might be something like 33, since I find there tends to be an 8 second delay on the 3DS)
First Pokemon: https://www.pokecheck.org/?p=detail&uid=2841732
Second Pokemon: https://www.pokecheck.org/?p=detail&uid=2840953

Since he was somewhat early in the game, I believe the only area with no WNPCs was the castelia park, so I went for that. The only NPC there is static and I believe it's not tied to the rest of castelia, so there should be no extra frame advancements.

FYI just south of Virbank is the earliest spot with no NPCs. Music is the same as the town, not in the area where the map and bgm changes.

We won't be able to use this data until we have some data from the game running on an original DS or DS lite. If you have access to one of those, could you do the same procedure there as well?

Also, do you have access to Korean Black 2, Black 1, and/or White 1? We need DSi/3DS info for those games as well.

The rare item table is located before the regular table.


It's pretty obvious how it works.

For the rare table, it starts off with the first two. For every 10 levels, shift down one row. Similar deal for the common table.

Obedience in BW2:
If the Pokemon's level is above number of badges * 10 a random call is made to see if the Pokemon will listen to you. The check is
if (rand(badges * 10 + level + 1) < badges * 10)

If this fails the Pokemon won't attack, there's a few different possible results.
First if some flag on the Pokemon is set it will always loaf around.
rand(0x100) is called and compared to (level - badges * 10).
Depending on the result of this comparison it'll fall asleep, display "wont obey" or display "is loafing around". I'm a bit tired so I haven't managed to exactly grasp the C code behind the comparison for these 3 different states. I'm mostly mystified by sub_21A0B68. Here's the assembly:
