This simple project illustrates a simple example of the GDMO API
You can use this API to make extensions similar to MHV7
The download link is in the releases
To use this API it is expected to know how to setup a basic c++ project and write some code.
You will find a GDMenu.lib file and an API.h file in the download;
Add the library file to your project libraries, and simply drag the API.h file like it was any other header file.
You should now be able to use the api; see the example project above for simple usage.
Once you've compiled your dll, simply drag it into GDMenu/dll.
