This is the first pokémon games on the nintendo 3DS and one of my all time favorites. Special thanks to Randal for letting me upload his guide here. I have also edited some parts to better match the english version of the game. All with Randal's consent off caurse

Chapter 1: introduction.

When you load the game you will have to choose the language. ´If you want to play in English press A twice, and if you want to play in Spanish go down one and press A twice. Then you will start listening to the intro music of the game. If you press A once more the game will start and a cutscene will be presented with Professor Sycamore welcoming you, showing you the Pokémon and that sort of thing. Skip the dialogue with b until you can't, it will ask you if you are a boy or a girl, press A 2 times to confirm. The first option is Boy, second is Girl. You will hear  the confirmation sound. Then you will have to choose your appearance, select the one you want. Finally, you must write your name, here the keyboard:
In the first row there are symbols and numbers that I don't know exactly how they are distributed. From the second row (one down) the distribution of the letters is as follows
qwertyuiop finish
a s d f g h j k l ñ ç
z x c v b n m
When you write your name it will say the typical stuff, your adventure is about to begin and other unimportant things, press B until the music stops.
Note: I'll explain the options menu when you get your first Pokémon and the pokedex. Even so, if you want to save the game at some point go to the menu, one up and  A 2 times to save. 
Note 2: get used to walking with the d-pad. The game will later  give you skates and the circle-pad is used to use them. And trust me, the skates are quite complex to use, especially in small places.
As always, you start in your room. The character will be sleeping, but will be awakened by a Fletchling. Then the relaxing music of Vaniville town will play. Before starting go to the menu, one down, one right to go to the options, press A, one to the right to set the text speed to fast, press B and press A to save.
Now close the menu and go one up, 5 right, one up and press A 2 times to change clothes. Close the dialogue and go all down and all right until you go down the stairs. When you do, a dialogue will start with your mother who will greet you and suggest that you go to greet the neighbors.
When the dialogue closes go 4 left and 3 down to leave your house. After a few seconds two girls of the same age will arrive (or a girl and a boy if you chose to be a girl). They are Serena (Calem if you chose to be a girl) and Shauna. They will welcome you to the town and tell you that Professor Sycamore, a renowned Pokémon scholar, lives in the region. and That he has asked for the help of 5 individuals. After a few words, Serena will suggest going to the next town and they will both leave. To go there go one left, all down, 6 left and all up, you will reach the Sketch trail. Follow everything up, you will cross Route 1 and when the music changes, you will arrive at Aquacorde Town.
While in town, go upstairs for about 5 seconds and press B to skip a dialogue, it is your friends who are sitting in a bar and they will ask you to go with them. The other two characters are also in the bar. To enter go 5 left. Your character will sit with the others and Serena will make the introductions, skip this dialogue with b. After introducing herself, she'll introduce you to Tierno, who loves music and dancing, and Trevor, who gets good grades but never brags about it. Then they will ask you to choose a nickname so that they can get closer. Serena will suggest the nickname Super and the initial of your name, in my case super R. Shauna will suggest the nickname Peque, and Trevor will suggest the nickname mr. When you no longer hear the typical text noise from pressing B, you will have to choose one of them. The first is small, the second super and the third mr. After you choose your nickname press select 3 times and skip the dialogue with B.
And here comes the interesting part. Tierno will ask you to choose a Pokémon. When you no longer hear anything when press B, you will have the option of choosing one. The first is Chespin, a grass type. On the right is Fennekin, a fire type. And to the right of this is Froakie, water type. To choose it press select 2 times. Remember that it will ask you to give it a nickname, if you don't want to do this just press B until you hear a different sound. Serena will choose the Pokémon that has the advantage over yours and Shauna will choose the last one left. Followed by this, Tierno will give you the pokédex and explain what it is. After a bit of talk, he will give you a letter that the professor has given him for your mother and he will go with Trevor to look for Pokémon, skip all that dialogue.
Before continuing I will tell you how the menu options are arranged.
First of all, you should know that there are thri rows and two columns.
In the first row is the Pokémon option, on the right Pokédex.
Below you have items, and on the right the trainer card. This will show you name, pokédex, money, time played ETC If you press select 2 times (or once when you have already entered) your trainer card your badges will be shown.
Finally, in the third row is save game, and on the right options.
The pokémon menu are divided into 3 rows and 2 columns. Your first and second pokémon will be in the first row, third and fourth in the second row and fifth and siksth in the third row. If you want to know the information of your Pokémon, press select. There you will have the following options:
summery: if you enter here you will have 2 columns. In the first you will be able to know things like name, ability, equipped item and moves. If you press select again, you will be able to order the position of its attacks by pressing select on one of the attacks and select on the attack you want to change its position with the previous attack. In the second column you will be able to know its nature, date you found it and place of origin,
heal: When you enter this, all your healing items will be shown. Press select on the item you would like to use, select use and then select the pokémon you would like to give it to, the pokémon are in a list in this menu.
Items: which allows us to give an item to one of our pokémon, or use an item. You can also remove a held item and give it to another pokémon if you want.
Move: this option allows us to change the position of your Pokémon, as with attacks, you do this by selecting the Pokémon which you want to move, then select the one you want to change position with.
And to use the pokédex simply enter the pokédex menu, press select and the Pokémon that you have already seen will be displayed. If you have caught them, you will have their description below. If you press select on any Pokémon you will be able to know its habitat. That is all! Later I will explain the battle menu.
When the dialog closes you'll go all right, all down, 2 right and 2 down. A dialogue begins with Shauna who will call you and ask you to have a battle!
Rival Shauna, Pokémon she uses
If you chose Chespin: Froakie level 5.
If you chose Fennekin: Chespin level 5.
If you chose Froakie: fennekin level 5.
Before continuing I will explain how the menu is made up in battles.
The first option is to attack. One on the right is the option to switch Pokémon. Below the attack option is the bag option. And one to the right, escape. After the opponent's pokémon has been defeted the game will ask you if you want to switch Pokémon. This does not happen if your opponent only has one pokémon.
  To switch pokémon  press select once, the Pokémon you have on your team will appear. When you select the one you want to use press select again to switch.
As in Pokémon black and white / Pokémon platinum, The backpack is divided into categories, being as follows:
HP/PP Restore is top left, Poké Balls are top right, Status Restore is bottom left and Battle Items is bottom right. The items of each category appear in lists of 3, to go to the second list go one right.
When you defeat Shauna's pokémon she will heal your Pokémon and go away. Close the dialogue and go down until you reach your town, make sure you are hitting the bottom wall and go 3 steps to the right, all up, one left and one up to enter your house. As soon as you enter a dialogue with your mother begins, she will feel proud of you because you are already an official trainer and then the character will give her the letter. When reading it, she will give you clothes, a map and, after a bit of talk, she will say goodbye to you and the music will change. Go downstairs until you hear a beep. Then you will hear footsteps and the cry of a Rhyhorn. Following this, your mother will come out and say that the Pokémon is saying goodbye to you, since it has seen you grow up. When the dialogue is closed they will return to the house.
