Extract text from RGTW game maps (HAMBU)
To convert HAMBU maps to another format, you need RGTW Game Engine or other Game software.
To convert other file formats to the "Game Map File" file type, you need software like RGTW Game Engine or a similar tool.
A .HAMBU file is a highly specialized RGTW Game Map File created exclusively by Aidan's Funhouse. These files are used by the game engine to store level geometry, entity placements, spawn coordinates, and environment variables required to load a playable map in the game RGTW.
Because it is proprietary to the RGTW ecosystem, there is no mainstream software - like Blender or Unity - that natively opens or imports this format. It is strictly compiled to be read by the native game executable itself.
Users typically look to convert these files when they want to mod the game, extract map layouts, or edit the underlying level parameters. The biggest disadvantage of the .HAMBU format is its closed-source nature. The files are often unreadable in standard text editors, meaning modders hit a wall unless community-developed reverse-engineering scripts exist. Standard online converters fail entirely because the proprietary byte structure of the file is completely undocumented.
When handling game files like this, the most realistic target formats are structured data like JSON, XML, or CSV, assuming the raw configuration data can be extracted. Direct conversion to 3D geometry formats like OBJ or FBX is usually impossible without losing massive amounts of game-specific logic.
This is why standard tools give up, but you still have options. Since .HAMBU files are difficult to process, your best approach is pragmatic analysis. If our analysis detects a supported underlying or embedded format - such as plain text strings or standard archive compression - viewing or extraction may still be possible.
Convert.Guru analyzes your HAMBU file, detects the exact format, and lets you read the text inside.
If you want to convert HAMBU file to CSV, JSON, XML, YAML, YML, TOML, INI, CFG, CONF, DAT, DB or SQL, you can use RGTW Game Engine or similar software from the "Game Map Data Storage" 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 HAMBU, try RGTW Game Engine or another comparable tool in the "Game Map Data Storage" 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 HAMBU converter.
