Star Fox 2 is (as you may have guessed) the sequel to Star Fox, greatly opening up exploration and adding a large number of new features as well as the ability to play as Peppy, Falco, Slippy, and new crew members Miyu and Fay.It also introduced many now series staples, such as on range mode, the charge shot, vehicle transformations and voice clips(though to a lesser extent than latter games). Turns out Andross isn't actually dead (what, you thought that cube inside a polygonal white face was actually him?), and he's launched an all-out assault on the Lylat System. While the map is open to you to go anywhere you want, this is also true for Andross' forces, even when you're in levels - and for the most part they'll be heading toward Corneria. As such, the Star Fox team needs to liberate planets while making sure Corneria doesn't take too much damage, because if Corneria is conquered then Andross wins. Elements from the game were incorporated into Star Fox 64, Star Fox Command, and Star Fox Zero.

By the time the game was completed in September 1995, the Nintendo 64 was around the corner, complete with its own Star Fox title in the pipeline. While Star Fox 2 had been planned for release in 1996 or possibly '97, it seems Nintendo didn't want to cannibalize sales of its new console by giving the SNES a cutting-edge 3D game on its way out the door, and Star Fox 2 therefore got resigned to the dustbin of history - seemingly forever.

Prototypes of Star Fox 2 were leaked online as early as 1999, cementing its reputation as one of history's most famous unreleased games. Two decades after its cancellation, the finished game finally saw the light of day as part of the SNES Classic Edition, with the ROM getting dumped and leaked on the same day as the console's release. Star Fox 2 was also released for Nintendo Switch on December 12, 2019 as part of the console's online subscription service.

To do:
  • Regional differences.
  • Debate on if info about the pre-final (1995.09.20) and Japan final (1995.09.21) debug-enabled build should go here, or be given its own sub-page.
  • There's plenty of .CGX graphics found from the July 2020 leak such as a more progressed design of the unnamed human woman, and a 1993 title screen. Document them in a Development page. That also includes more unnamed cut animals from Corneria.

Test Menus

Star Fox 2 2017 Test Menu.png

On the main menu, use Pro Action Replay (PAR) code 03F0B603 to access the Test menu or 03F0B604 to access Training mode. Both of these options were present in the June 22, 1995 build, but were disabled for the final.

To restore the Test menu's functionality, use 7FFA2502 7ED7F402 7E1BC802.

These codes also re-enable the Expert Mode menu option by default (as was the case in the June 22, 1995 build), though selecting it redirects the player to the Test menu instead.

One noteworthy detail is the top-left corner of the menu, which lists the game's build date as September 12, 1995. Since the game's original release was cancelled outright there's no way of knowing for sure, but a build date of September '95 wouldn't be out of line for a Q1 1996 release.

Unused Areas

Early Secret Base


By promptly turning off the cheats after accessing the Test menu, selecting Venom level 06 sends the player to the earlier Secret Base that was seen in the June 22, 1995 prototype. This version appears to have been worked on since then, as the Homing upgrade is now present. However, due to there being no target to destroy, a stage clear message will display immediately upon entering and will send the player back to the Test menu.

Unused Text

Leftover Build Date

Present at 0xE07 in the ROM is a build string from an early prototype of the first Star Fox, when the game was intended to be a new entry in Argonaut's Star Glider series rather than an original Nintendo IP. (A build of Star Glider for the SNES was eventually leaked in July 2020.)


As strange as it is for this to be here, it's even stranger in that this string doesn't appear in any version of Star Fox itself.

Graphical Oddities

The graphic of the six playable characters displayed on the title screen has a few coloring discrepancies when compared to other character artwork seen throughout the game:

  • Slippy's necklace is blue on the title screen, but red in both his dialogue and Pilot Select portraits.
  • Peppy's scarf is red on the title screen, but green in both his dialogue and Pilot Select portraits.

Regional Differences

Intro & Title Screen

Japan International
Star Fox 2 Japan Carrier.png Star Fox 2 International Carrier.png
Japan International
Star Fox 2 J Title Screen.png Star Fox 2003.png

The S and F are raised in the logo for the international version, and level with the rest of the text in the Japanese version. The logo font as a whole is slightly different between the two, with the international logo's font using serifs.

Audio Differences

Japan International

In the Japanese version, Falco's voice shouts "Adiós, Andorf!" after the player defeats the final boss. The international version appropriately uses "Adiós, Andross!" instead.

Results Screen

Similarly to the Falco voice line in the ending, the results screen also changed the "ANDORF DESTROYED" text to "ANDROSS DESTROYED" in the international version.

Hidden Music

To do:
Rip the songs. See if they can be accessed in the sound test (does the sound test still exist in the final game?).

  • Waiting ten minutes at the ending screen after clearing the game on Expert mode will play some music heard nowhere else in the game. The music consists of an orchestral overture, followed by a lengthy pause, and finally a different song that loops until the player presses Start.

(Considering the long gap between these two thematically-different bits of music, it's fair to say they are probably two separate pieces.)

Controller Error

Japan International
SF2-ControllerPakJapanese.png SF2-ControllerPakEnglish.png

If the game detects that a Super Scope or SNES Mouse is plugged in either port, this error message will be displayed. This ended up going functionally unused, since the player is hard-coded to use a standard controller in the SNES Classic and Switch Online releases.
