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 very creepy 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 may be debug options at offset 43ABF0 of the executable (US, Rev 1)?
  • It seems Common/RP/HpeScene/common.carc and Common/RP/Hpe2Scene/common.carc consist entirely of unused content, including earlier versions of used models, a target model for the scrapped parachute game, unused levels for Table Tilt, as well as a ton of unused animations for Step Aerobics.
  • Prerelease content from E3 2007.

Unused Models

Soccer Heading

Common\RPHpe2Scene\common.carc\hdg.brres has an earlier version of the Soccer Heading field without footballs or a panda head being spread across the ground.

Common\RPHpeScene\common.carc\ball.brres has 3 Soccer Heading balls with different models and lighting compared to the final ones.

Common\RPHpe2Scene\common.carc\GateRing.brres is a ring associated with the Parachuting game. It resembles the one seen in the the E3 2006 Wii Sports Airplane demo., although it lacks the red stripes.

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

Common\RPHpeScene\common.carc\fencing.brres and Common\RPHpe2Scene\common.carc\fencing.brres contains the Wii Sports Boxing training ball, used for the scrapped Fencing game.

Common\RPHpeScene\common.carc\sabel.brres is a sabel model for the Fencing game.

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

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.
