Extract text from Kart Rumble files (KRM)
To convert KRM Rumble files to another format, you need Wiimms SZS Tools or other Game software.
To convert other file formats to the "Wii Modding File" file type, you need software like Wiimms SZS Tools or a similar tool.
The .KRM file is a Mario Kart Wii Kart Rumble File used to store force feedback (vibration) sequences for the Nintendo Wii Remote. These files dictate the intensity and duration of controller vibrations when a player drifts, crashes, or drives off-road in the game.
Modding communities rely on tools like Wiimms SZS Tools or BrawlBox to extract and manipulate these files. The primary disadvantage of the .KRM format is its highly specialized, closed binary structure. It is proprietary to Nintendo and completely unreadable by standard text editors, web browsers, or modern game engines. Because it is strictly tied to the Wii hardware, modifying it directly is impossible without specialized software.
Users typically need to convert .KRM files to structured text formats like XML or JSON. This allows modders to manually adjust the vibration parameters for custom tracks and karts before compiling the file back into the game archive.
This file format is exceptionally difficult to open or convert because standard online converters fail to process undocumented, proprietary console formats. Often, only community-built reverse-engineering software can properly read or export the data.
Convert.Guru analyzes your KRM file, detects the exact format, and lets you read the text inside.
If you want to convert KRM file to CSV, JSON, XML, YAML, YML, TOML, INI, CFG, CONF, DAT, DB or SQL, you can use Wiimms SZS Tools or similar software from the "Force Feedback Rumble Data" category. In the File menu, look for Save As… or Export….
To convert DBF, XML, SQLITE, XLSX, SQL, TSV, ACCDB, YAML, MDB, CSV, ODS or JSON files to KRM, try Wiimms SZS Tools or another comparable tool in the "Force Feedback Rumble Data" category.
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our KRM converter.
