You're welcome. We're still active, but we are just a few (and mostly spanish).
The next step if to find out why your .bat file don't execute your game.
In my case, I have a few BennuGD binaries in a separate folder, with all the libraries, instead of copying them in the same folder as you do. Then, I use a bat file like this:
bgdc -g %JUEGO%.prg
So, I can compile with the binaries in C:/BennuGD/Binaries/r307 (the "bin", "externals", etc folders are for backwards compatibility) and the project (and this .bat) in C:/BennuGD/Projects/MyProject. It's cleaner this way. Also, I make another .bat just for compilation, to see the compile errors.
The -g parameter in BGDC is for debug mode, so I can hard-close the program with ALT+C.
