F-Zero: Maximum Velocity Password Decoder

A JavaScript-based F-Zero: Maximum Velocity Rankings passwords decoder.

How to use

Note: these steps won't work for save files where no record in any track has been set.

  1. Open the desired save file.
  2. Select Rankings and select the desired cup (works with Championship too).
  3. Select the player's name (won't work with Mixed Rankings).
  4. Select the desired track.
  5. Press in sequence Up, Right, Right, B, Left, B, Right, A while holding L.
  6. If done correctly the track's subtitle will be replaced by a password.
  7. Write down the displayed password.
  8. Open https://waluigibsod.github.io/fzmv-password-decoder/.
  9. Enter the password (e.g. -+045Q=R=HFLX6Q9HNRC).
  10. Read the decoded info.

Program

It's basically a fork of Version 1.5.2 of Dr. Mario 64 Password Decoder, another tool I wrote. Obviously the decoding algorithm is not the same.

Both this program and F-Zero: Maximum Velocity Password Generator were written using the original source code of the game that leaked in July 2020 as reference.

The original implementations of the password generation and decoding algorithms inside the source code of the game can be found at netcard.7z\iqgba.tar\iQue-GBA\cvsroot\FZERO_for_GBA\rasheen\src\main\ras_codec.c.

An additional file that was used as reference is netcard.7z\iqgba.tar\iQue-GBA\cvsroot\FZERO_for_GBA\rasheen\src\p1\ras_game_dat.c, for converting vehicle IDs to names.
