Pressing A/B/Select/Start at the same time while playing the game will return you to the title screen.

While on the title screen, pressing Left/Select/B at the same time will erase the current saved game.

Due to screen size limitations on the Game Boy, a feature was implemented where if you pause the game while outside, you can view the rest of the stage using the D-Pad. This cannot be done inside rooms and shops.

Pit was first depicted with blue eyes and a laurel crown in promotional artwork for Kid Icarus: Of Myths and Monsters, which was not released in Japan until 2012. If the eye color and crown of Pit's design in 2008's Super Smash Bros. Brawl was influenced by Of Myths and Monsters and wasn't simply a coincidence, that would make it the first and so far only instance of Super Smash Bros. referencing content from a game without any kind of Japanese release at the time within gameplay, and shared with a sticker originating from Of Myths and Monsters as the first representation of a game without a Japanese release whatsoever outside of the Chronicle (which is also technically tied with trophies in the same game from Elite Beat Agents, a heavily modified localization of Osu! Tatakae! Ouendan).
