Extract text from Game Maker 6 projects (GM6)
To convert GM6 projects to another format, you need Game Maker 6 or other Developer software.
To convert other file formats to the "Game Engine Project" file type, you need software like Game Maker 6 or a similar tool.
The .gm6 file is a proprietary game development project created by Game Maker 6, originally developed by YoYo Games. It stores uncompiled game assets, including sprites, sounds, background images, and GML (GameMaker Language) scripts in a single working file. These files allow developers to design, test, and edit 2D games before compiling them into standalone executables.
The main disadvantage of the .gm6 format is that it is obsolete, closed, and highly proprietary. Modern web browsers, image viewers, and standard text editors cannot natively read it. Furthermore, modern versions of GameMaker Studio have completely dropped direct support for .gm6 files. This creates a massive bottleneck for developers who want to update old projects, as they are forced to track down legacy software (like Game Maker 8) just to open the file.
Standard online converters fail to process this format because only the original software understands the proprietary binary structure and custom asset indexing. You cannot easily convert it to a modern format without a staged software migration path to gmk or gmx.
Drag and drop your .gm6 file into convert.guru to see what it is and convert it if supported. While full project conversion requires the original engine, our tool can often inspect the proprietary binary structure to identify the file format, show text or internal content, and occasionally extract underlying formats like PNG or WAV when standard methods fail.
Convert.Guru analyzes your GM6 file, detects the exact format, and lets you read the text inside.
Users also converted GB1, GMR and GM1 files.
If you want to convert GM6 file to JS, TS, PY, JAVA, CPP, C, CS, PHP, RB, GO, RS or SWIFT, you can use Game Maker 6 or similar software from the "Game Development Project Storage" 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 GM6, try Game Maker 6 or another comparable tool in the "Game Development Project 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 GM6 converter.
