This is why I don't believe a word from the author. I don't even know if the demo is actually translating it or a demo of how he wants it to work. I have no idea if 90% of it is hand translated (SDL, some complex routines, etc) with the easy 10% actually translated.

Or maybe 100% of it isn't translated but compiled to object files with a compiler with V generating wrapper functions. I have no idea what to expect

I just never heard of anyone using V and it actually working as they expect
