Gallery Corner

The Gallery Corner is a location in the Game & Watch Gallery series that houses the Note Board, the Music Room, the Museum, the Gift section, Secrets (Game & Watch Gallery 3 only), and G&W History (Game & Watch Gallery 4 only).

Game & Watch Gallery 2
The Gallery Corner first appears in Game & Watch Gallery 2, where the Gallery Corner has four sections: the Note Board (initially available), the Music Room (five stars required), the Museum (ten stars required), and the Gift section (permanently available after collecting 100 stars). With 55 stars, the Music Room can be upgraded.

Game & Watch Gallery 3
The Gallery Corner reappears in Game & Watch Gallery 3, where the Gallery Corner holds the four sections used in Game & Watch Gallery 2 as well as Secrets 1 (15 stars required) and Secrets 2 (60 stars required). In Secrets 1, a sample of the reversed Fire is shown. In Secrets 2, the reversed Fire becomes playable.

Game & Watch Gallery 4
The Gallery Corner reappears in Game & Watch Gallery 4, where the Gallery Corner holds once again the four sections used in Game & Watch Gallery 2 as well as G&W History (70 stars required), a timeline about the original release date of every Game & Watch title released.

Game & Watch Gallery 2
In this game, the Gift section controls when Ball (both versions and all 4 character variants) is unlocked. Going through here is required to unlock said game, and it instantly redirects to Ball after permanently unlocked.

Game & Watch Gallery 3
In this game, the Gift section is now hosted by Mario and Peach, at daytime (with a wall as a background). They show the player the secondary games that has unlocked. Peach shows some stuff when presenting the secondary games, like a Game Boy Color, a flag (when presenting Flagman), a hammer (when presenting Judge), a star (after collecting 30 stars), a lion plush, (when presenting Lion), a block (when presenting Spitball Sparky) and a Donkey Kong plush (when presenting Donkey Kong II). A pedestal also shows the secondary games' handhelds. Like Game & Watch Gallery 2, going through here is required to unlock the secondary games.

Here's a complete list of Peach's lines:
 * When unlocking Flagman: "Have you played all games yet? There are more classic Game & Watch titles. For starters, I'll give you Flagman. Game A and Game B are different. Remember which button shows which number."
 * When unlocking Judge: "Are you getting used to playing? For your efforts, I'll give you Judge. Hit your opponent if it's a higher number. You can link with a friend to battle."
 * When unlocking Lion: "Seems like you're getting lots of stars. For more fun, I'll give you Lion. Use two men to push lions into the cage."
 * When unlocking Spitball Sparky: "Thank you for playing so much! Want more? Then take Spitball Sparky. Delete all blocks to go to the next stage. Guess how many stages there are."
 * When unlocking Donkey Kong II: "You've come a long way to get up here! The last gift is multi-screen Donkey Kong II. The basic rules are similar to those of DK Jr.."
 * Before unlocking credits: "You can collect more stars to open more events."
 * After unlocking staff credits: "Again, here's the impressive game finale. To see the credits screen, press A."
 * After unlocking both credits: "Again, here's the impressive game finale. To see the credits screen, press A. Press down and A to see character credits."

Game & Watch Gallery 4
In this game, the Gift section is now called Present, taking place indoors (with some gift boxes, toys, and plants as a background), and it is hosted by Mario and Mr. Game & Watch. They show the player the secondary and tertiary games unlocked. Before the handheld is shown, a ? Block falls from above and then morphs into the corresponding secondary or tertiary game's handheld. Unlike in Game & Watch Gallery 2 and Game & Watch Gallery 3, going through here is no longer required to unlock the secondary and tertiary games. After unlocking every secondary/tertiary game, the player will be redirected here, and after presenting every secondary/tertiary game, the player will be redirected to the Game Select screen (for secondary games) or the Museum (for tertiary games).

Here is a complete list of Mario and Mr. Game & Watch's lines:

Mario: Have you played all of the games yet?

Mr. Game & Watch: There are still more Game & Watch titles.

Mario: For starters, I'll give you Chef.

Secrets
"This is Fire, introduced in Game & Watch Gallery 1. Don't you think something is wrong with it? The truth is, this Fire is reversed left to right. This version was planned to be released as is. The LCD designer happened to make it incorrectly. Nevertheless, the game was such as playable. It was released as it was. So far, it seems OK. This Fire is now hidden at Gallery Corner. Why don't you collect enough stars to play it. Well, that is all I wanted to say. See you around!"

- Mario

Appearing only in Game & Watch Gallery 3, the Secrets section has 2 parts: In the first one, Mario presents the reversed Fire while an animation of said game plays. In the second one, the player can choose to play the reversed Fire or not. The reversed Fire, has some features and differences:
 * Pausing is not possible, pressing will redirect the player to the Gallery Corner.
 * After getting a Game Over, the game will instantly stop. Reentering the Secrets 2 section is required to play again.
 * The game behaves similar to its Wide Screen version, but its appearance is from its Silver Series version.
 * The ambulance's lamp will light up when an evacuee is saved (does not give any extra points).
 * Its score font was previously used in Game & Watch Gallery.

G&W History
Appearing only in Game & Watch Gallery 4, G&W History shows the original release date for every Game & Watch game (including non-Mario related ones).

Here is the complete list of G&W History:

Some curiosities and errors are:
 * Crab Grab is misspelled as Crab Crab.
 * Mario the Jugglers release date says "October 1982," but the real release date of that game is October 1991'.
 * The NES appears in this list because it was released during the Game & Watch era.

Trivia

 * The illustration used for Game & Watch Gallery 4's Note Board says "Mario's Circus" (possibly because of the amusement park as a background).
