1.) Hmm. Not sure why it is freezing but I will look into compiling a 64 bit version.
2.) I'm not sure what programming language or game making app you're using but are you able to call on the DLL I've provided? It's available for download too.
I hate do admit it, but I don't really know how to call on a DLL. >.< I don't really understand DLLs, UIs, Visuals, or Sounds in general since I don't get the numbers associated with them. I am still learning what numbers go with what colors, what numbers go with what visual elements, and so on.
Rather than a programming language, coffeescript and javascript would be script languages? Visual Novel Maker primarily uses json files for storing information and uses programming language for the launcher from what I know, but otherwise uses scripting language for a lot of the functions that can be modified.
It should be possible. Would you be able to if I could figure out how? (I was told that it could be done, but I need to read the documentation to figure out how it works)
And if not, I'm in no major rush if you'd be willing to do make a javascript version later on.
Anyways, let me know how much it would cost to have a 64 bit version made.
