About NDLL files
A .ndll file is a Neko Dynamic Link Library, essentially a standard native plugin renamed for exclusive use by the Neko Virtual Machine. These files act as the bridge between high-level Haxe code and low-level operating system functions, handling critical tasks like graphics rendering, audio processing, and networking.
Because .ndll files are compiled binary executables (just like EXE or DLL files), they cannot be "opened" or edited in a text editor. A common friction point for developers and modders is trying to debug these files, as they are proprietary to the Neko environment and often lack documentation. While you cannot convert an .ndll directly into readable source code, you can rename it to DLL (on Windows) to inspect its dependencies and exported functions using tools like Dependency Walker. For archiving or distribution, they are often packaged into ZIP archives alongside the main executable.
Convert.Guru analyzes your NDLL file, detects the exact format, and lets you read the text inside.
If you want to convert NDLL file to JS, TS, PY, JAVA, CPP, C, CS, PHP, RB, GO, RS or SWIFT, you can use Neko Virtual Machine or similar software from the "Neko VM Plugin" category. In the File menu, look for Save As… or Export….
To convert SH, PY, KT, PS1, SWIFT, LUA, PL, JAVA, SCALA, JS, VBS or TS files to NDLL, try Neko Virtual Machine or another comparable tool in the "Neko VM Plugin" category.
The NDLL Converter Story
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 NDLL converter.
