Badge image data
Following the badges metadata is it's image data. Each badge contains multiple images used in different places during gameplay
An image can be either RGB565 or ETC1A4. RGB565 images are immediately followed with A4 data for itself, whereas ETC1A4 images are immediately followed with A8 data for itself
A badge may take up multiple spaces on the Home Menu, and as such contains images for each space called "tiles". The number of image tiles a badge uses is found in the badge metadata at offsets 0xB8 and 0xBC
All badge image data begins with a 64x64 RGB565 image of the full badge. Following the 64x64 image is a 32x32 RGB565 image of the full badge, which is used in the badge selector in Home Menu
If the badge is 1x1 tiles, then the first 64x64 RGB565 image is used in Home Menu to display the badge. If the badge is not 1x1, then the badge contains x*y number of additional 64x64 and 32x32 RGB565 images, where x is the number of horizontal tiles and y is the number of vertical tiles. These tiles are then used in Home Menu to display the badge. These additional images are stored immediately after the 32x32 image
Finally, the last image in the badge image data is a single 128x128 ETC1A4 image of the full badge which is used in game
| Offset | Size | Description |
|---|---|---|
| 0x1100 | 0x2000 | 64x64 RGB565 image of full badge (used in Home Menu if badge is 1x1) |
| 0x3100 | 0x800 | A4 data |
| 0x3900 | 0x800 | 32x32 RGB565 image of full badge (used in badge selector in Home Menu) |
| 0x4100 | 0x200 | A4 data |
| 0x2000 | 64x64 Optional additional RGB565 image tile(s). Only exists if badge is not 1x1 (used in Home Menu if badge is not 1x1) | |
| 0x800 | A4 data | |
| 0x800 | 32x32 Optional additional RGB565 image tile(s). Only exists if badge is not 1x1 (unknown use) | |
| 0x200 | A4 data | |
| 0x4000 | 128x128 ETC1A4 image (used in game) | |
| 0x4000 | A8 data |
Language Names
Some files, like the badge and the category file, store its display name in a set of 16 different languages.
Each language is stored as a little-endian utf16 string, in an allocated 0x100 byte section stacked on top of each other.
A string does not need to fill the entire 0x100 byte section, the remaining data is set to null bytes
The languages are ordered as follows:
- Japanese
- English
- French
- German
- Italian
- Spanish
- Chinese (simple)
- Korean
- Dutch
- Portuguese
- Russian
- Chinese (traditional)
- Unknown

Collision data
The collision of an object is defined by a set of polygons combined together.
The polygons are represented using the vertices of each polygon, and those vertices are represented using their coordinates according to the in game image resolution.
| Offset | Size | Description |
|---|---|---|
| 0x0 | 0x4 | Number of polygons |
| 0x4 | 0x44 | Polygon data |
| 0x44 | Additional polygons data |
Polygon data
The data of a polygon starts with the number of vertices. The coordinates of each vertice are then stored as float32 values on an allocated 0x40 byte section.
If the coordinates don't fill the 0x40 byte section, the remaining data is set to null bytes.
| Offset | Size | Description |
|---|---|---|
| 0x0 | 0x4 | Number of vertices |
| 0x4 | 0x4 | X coordinate of vertice |
| 0x8 | 0x4 | Y coordinate of vertice |
| 0x4 | X coordinate of additional vertices | |
| 0x4 | Y coordinate of additional vertices |
