Wii Fit is an exercise game that uses the Wii Balance Board for a bunch of different minigames, as well as doing yoga with a woman who somehow became a fighter in the Super Smash Bros. series. The game was a huge success, and even spawned a sequel.

To do:
  • There are also textures for the rest of the sports balls from Wii Sports and Wii Play.

Balance Test

Common\RPHealthBalance\common.carc has four brres files for some sort of test with a ball, goal, seesaw, and... stop!!

Realistic Trainer

To do:
Make GIFs of the animations.

Common\RPHealthMainScene\common.arc has a model of a more realistic female trainer with textureless, solid-color clothes.

Wiifitplus realistictrainer.png Wii fit plus realistic trainer body.png

Based on the structure of the model and the full version of her body texture, it is apparent that the model was originally nude and the developers simply retextured parts of her body to create her clothing. The color of her clothes roughly match that of the normal trainer in the original Wii Fit. (They appear white in the image due to a rendering error.)

The clothing meshes have their UV data removed, making them unable to use the body texture. The trainer has a few animations of some warm-up stretches and yoga poses, but her shoulders get distorted and inverted due to how they are rigged. Additionally, while the warm-up poses flow together, the yoga poses (different steps of the Tree pose) are almost completely still and have no transition between them.

Unused Graphics


Common\RPHealthCommon\common.carc has two unused dummy textures. The first one, "仮", translates to "temporary".

LayoutCommon\RPHealthTraining\common.carc has two unused textures which are of a person breathing.

Common\RPHealthCommon\common.carc contains a file called icon_checkpoint.bti, which could be a icon for a checkpoint, as the name suggests, in the unused Balance Test game.

LayoutCommon\RPHealthBalance\common.carc has an unused texture of a placeholder image for the Balance Test minigames. "仮", translating to "temporary"

Common\RPHealthTraining\common.carc has a file called item_test.brres, which has instructions on meditative breathing.

Wii-Fit-Tj dummyFace 00.tpl-0.png

In various files, a placeholder graphic of a very blurry Mii face can be found, likely most often used as placeholder Mii faces in games like Table Tilt.


Layout Common\RPHealthMenu\common.carc has unused icons for the Training Menu, showing locked icons for minigames that are normally available on a new profile.


Common\RPHealthMainScene\common.carc has three icons of Tree Pose.

Unused Animations

Body Test

Common\HealthShared\common.carc\avatar.brres & Common\Hpe2Scene\common.carc\health_test.brres contain unused animations for the Body Test, most of which include what animation your mii will do when the game calculates your BMI and Wii Fit Age.

Balance Bubble

Common\HpeScene\common.carc\avatar_ira.brres contains unused animations for Balance Bubble, mainly having to do with how your Mii moves inside the bubble.

Basic Step

Common\HpeScene\common.carc\avatar_step.brres contain unused animations for Basic Step, which were earlier animations for the Miis stepping on and off the balance boards. These animations look similar to the ones used in the E3 2007 trailer for Wii Fit. It seems like the Balance Boards were positioned higher up when these animations were made as the Miis float a bit above the Balance Boards when the animations are used.

Unused Text

Fit Credit Unlocks

There is unused text in US\Message\health_message.bmg that would have implied that you would have had to unlock more training games, rather than already having those games unlocked as in the final game. It seems that Soccer Heading and 2P Run would have been the only games that would've been already unlocked.

Basic Step

Unused text in US\Message\health_message.bmg suggests that Basic Step would have originally have had an Advanced and Expert Difficultly, instead of Advanced being a separate game and Expert being completely unused in the final game.

You're getting good at this. Unlocked: Advanced
You're getting good at this. Unlocked: Expert

Lotus Focus

Unused text at entry ID 2600192 in US\Message\health_message.bmg suggests that Lotus Focus would have had subtitles for the announcer.

Katsu! Sit still.
And that's the end.

Camera Scripts

To do:
Double check if this applies to other regions.

In the USA Rev 1 edition, two csv files are left behind in "Common/RPHealthMainScene/common.carc" in its "chart" folder. One named "radio_gym_00.csv" and the other "実験トレーニング_データフォーマット.csv" (roughly translating to ExperimentalTraining_DataFormat), they describe camera actions, timing, sound, animation and sequences.

Installation Info

Present in InstallInfo/HealthNand#$.txt is a log-kind of file (presumably meant for the the game's channel) where according to the internal developer wiki, these files are titled the way symbol maps are.

# is the destination (game region) and $ is Target (build target) (i.e. "UP" is US Product). Interestingly, it mentions most likely the internal name of the game's channel.

Debugging Material

Build Display

Oddly not stubbed out in product builds of the game is a hidden display for the product build date.

According to the developer documents in an internal developer wiki found in the 2020-09-09 Nintendo leaks, pressing A, D-Pad Up, 2, D-Pad Down, B, 1, 1, B, D-Pad Left, A, D-Pad Right at the title screen will show a display in the bottom-right corner in black for the region and product build type (found in the executable) and also print out the data in timeStamp.txt until the scene is exited. There is no sound cue.

Performance Meter

WiiFit performanceBar.png

The game's code initializes an instance of the ProcessMeter from the EGG library, used by some first party Wii games. The green one measures the CPU sending commands to the GPU, the blue one shows the GPU rendering from said commands, and the red one displays the total frame time.

In one of the initialization functions (RPSysSystem::setup0), the game deliberately hides the performance bar from the screen (at 0x801850c8 Europe Rev 1. To show it, use the Gecko code below:

Europe Rev 1
Gecko Code
041850b8 38800001

Exception Handler

WiiFit exceptionhandler.png

The exception handler from the EGG library is present. When the game crashes, press the following buttons (in order, from left to right) on the 1st Wii Remote (Vertical) to bring it up:

HOME, A, B, 1, 2, -, +

Use the D-Pad to scroll.

Unreleased Chinese version

The Taiwanese disc contains files from the unreleased iQue Wii (Chinese) version of Wii Fit.

Simplified Chinese Wii Fit Channel Banner

The Taiwanese version includes an unused Simplified Chinese banner (with the "Channel" string displayed as 频道) that can display if the console's language is set to Simplified Chinese.

Simplified Chinese Safety Screen

Found in LayoutCommon/RPHealthTitle/common.carc/HealthStrap.arc are the strap/safety screens in Simplified Chinese. These match the ones present on Mario Kart Wii.

ChineseStrapScreenWiiFit1.png ChineseStrapScreenWiiFit2.png ChineseStrapScreenWiiFit3.png

Simplified Chinese Channel Installer

Attempting to install the Wii Fit Channel from the Taiwanese version of the game while the system is set to Simplified Chinese, the game will instead display the installer's unused Chinese translation.
