I must admit, I don't really understand what's causing the hold up. There is an SDK (albeit potentially unofficial, but does that really matter?) and the A320 has various open source emulators that would simply need a recompile for the A330. I don't know how to do it, but there's dozens of people on this board who do, so why isn't anybody doing it!? If, as far as I understand, all you need to do is load up the source in the SDK and re-compile it with minor tweaks such as screen size and buttons, it surprises me there's so many people moaning and so few doing.
I understand some people want Dingux but that doesn't mean the native stuff has to suffer!
