You will be able to access the EXTRA menu after you clear the game for a first time. This menu stores additional features of the game such as trial maps, tutorials, background music sound rom and battle forum.
Trial Maps

The trial maps are extra maps where players have a mission to complete, such as defeating the boss or keeping units alive, somewhat similar
to the in-game maps. For trial maps, please visit the Triap Map page from the left menu bar of the site.
Battle Forum

The battle forum allows players to practice character battling with the system, or to connect up to 4 players to battle against each other.

First the player has to form his own team by clicking the first option on the submenu. You will be able to choose from which file you get the
characters. A most of 5 characters are allowed on each team.

Then of course, you give your team a name. Each player can make multiple teams, but you can only choose one team to battle each time.

Now after you finish chosing your team, you will enter the arena with your opponent (either the computer system itself for 2-player battle or as many
as up to 4 players.)

The team that marks P1 (player 1), which is usually you if you are playing with the computer, will go first by choosing your own unit and one
of your opponent's units. You cannot see the stats of the opponent's units until after you battle them for the first time. The battling system
in this forum is the same as inside the game.

After every battle, you will be awarded points depending on the weapons you used, the damage caused to your opponent and the level of your unit.

After every but one team is all down, the remaining alive units will gain 30 points per head to their team. Final results will be shown.

You can also check the ranking of each of the different classes used in the battles. (I am not very sure how to read the following result table...)

Tutorial

I have no idea why they put up this tutorial only after you have beaten the game once. In short, this tutorial is similar to the first chapter of Rekka
no Ken (FE7) if you have played it. Cecilia will be teaching you (with Roy) how to walk across the grid, use potions, attack, end turns, get units
to join etc...

Sound Rom

In the sound rom option you can listen to all the background muci (bgm) played inside the game. Press the A-button to start playing a track,
press the B-button to stop it, left and right buttons to go through the list and the start button to exit the sound rom.
