There is a secret level that can be reached from the Asteroid Field in Level 3. Getting there requires destroying the second of two large asteroids and then flying straight into the bird that appears. Doing so results in being transported to "Out of this Dimension" where the background is warped, the enemies appear to be floating pieces of paper, and the boss is a giant slot machine. Once defeated by getting three 7s, the end credits roll and the player is stuck in this level until the game is reset.

The English manual for Star Fox infamously states that the Lylat System is located "near the center of the Milky Way galaxy". However, this appears to be a localization quirk on Nintendo of America's part, as the original Japanese manual states that Lylat is located simply "near the center of a vast galaxy".

After the release of Star Fox 64 3D, Dylan Cuthbert and Q-Games had pitched doing a similar style of remake for the original SNES Star Fox title. However, this was turned down by Nintendo.

Star Fox, Star Fox 64 and Star Fox Adventures are the only Star Fox titles to provide official ages for the main characters, primarily within their Japanese ancillary material. In the Original Soundtrack box released for the first game, Fox, Falco, Peppy and Slippy are said to be 25, 28, 36 and 19 respectively. Star Fox 64, being a remake of the first game, would retcon these ages and make Fox 18, Falco 19, Peppy 41 and Slippy 18.

The "Farewell Beloved Falco" midquel manga, which is set right in the middle of the eight years between Star Fox 64 and Star Fox Adventures, also gives the original Star Fox crew ages, with Fox now being 22, Slippy 22, Falco 23, and Peppy 45.

Star Fox Adventures takes place eight years after Star Fox 64, which means that Fox is now 26, Falco 27, Peppy 49 and Slippy 26. Japanese Star Fox Adventures ancillary material also reveals Krystal's age to be 19, making her distinctly the only Star Fox character outside of the original four Star Fox members to have a known age. Going by this, she would be 11 and 15 years old during the events of Star Fox 64 and Farewell Beloved Falco, respectively.

After Adventures' release, Nintendo, specifically Takaya Imamura, made a deliberate decision for future Star Fox games to not provide any official age numbers for any of the characters. However, Star Fox Assault officially is said to take place only year after the events of Star Fox Adventures, so this would make Fox 27, Falco 28, Peppy 50, Slippy 27, and Krystal 20. Similarly, according to Takaya Imamura in a 2007 interview, Star Fox Command takes place 2-3 years after Assault, which would make Fox 29-30, Falco 30-31, Peppy 52-53, Slippy 29-30, and Krystal 22-23.

Although Wolf O'Donnell has never had any age officially listed for him, Takaya Imamura implied on Twitter that he is within the same generation of Peppy and James.

Star Fox Composer Hajime Hirasawa left Nintendo shortly after the game released and six years later founded Faith Co. Ltd, the company that developed the world's first downloadable ringtones.

On the Continue screen, Fox can be seen standing alongside a grid display showing off the 3D model of an Arwing, which can be interacted with.

Controls:
• D-Pad = Rotates the model; pressing or holding down in one direction will cause it to move faster; doing so in the opposite direction will cause it to slow down; doing so in a perpendicular direction (i.e. pressing either left/right and then pressing either up/down, or vice versa) will not affect the speed of the model.
• X button = Stops the model's movement; moving with the D-Pad resumes it.
• L and R buttons = Zooms in and zooms out the model respectively.
• A button = Holding this button triggers a "drawing" mode where a still image of the frame where the render last appeared will trail behind it infinitely with each succeeding frame; this effect is similar to the "trailing/ghosting" glitch that can occur when dragging windows or dialog boxes on older computer operating systems.
• Plugging in a second controller = Every button except for L, R, X and A, will let you scroll through numerous models of enemies found throughout the game.
