I already bugged everyone in the 1.25 forum. I hate hoaxes. If this is a hoax. Well, uhm, then I would find it obvious. Besides, if it weren't a hoax, (for agument's sake,) record a better video. I would think that only support of multy tileset is not enough to convince someone. Here's what would convince me:

-Multiple tilesets.
-A new character.
-Different Jazz 2 logo.
-New weopon (must be switched to and fired.)
-Tweedle Boss.

If you can change the source, you can surely do that.

P.S. How did you get the source if this isn't a hoax? If through e-mail, I wanna see the message.
