Just three questions before I donate:

1.) What's the region of the game
2.) Has the game been displayed in media form before (magazines, videos, screenshots, etc). I know you said "It's an unreleased game which doesn't have any playable representation available to the public", but I'm talking about in the form of media besides a playable demo.
3.) Can it run in SSF (or any emulator for that matter) without any problem?

That's all, it shouldn't ruin the surprise - at least for me anyway. :)

Thanks for all your hard work. You guys have been a super addition to the community.
