It's ok to submit a 2K or 4K ROM, if only 1K is used and 
the rest is zeros.

That is a *bug* in the description. One obviously can't 
follow this instruction, since you need the startup 
vectors. :-)

Try this at the top of your source:

	ORG $F800
	ORG $FC00

Now the first 4 pages of the ROM should be zeros and the 
last 4 should contain the 1024 bytes of your game.

That would be a valid 1K entry in a 2K binary.
