But the game is ORGed at $f000, so it uses only the address space between
$f400 and $f7ff. How can it hit any hotspots then?

And the game crashes *after* pressing the fire button (which causes 
executing BRK), so the graphic data at the end of the ROM can't be the 
reason. Right?

The BRK might be the reason. IIRC, Makewav and Playbin map the 2K
into $f000-$f7ff, if the reset vector points into that area. That
means that there is nothing at $fffe-$ffff to provide a proper
BRK vector. So doubling the binary to 4K might help. Or you
could ORG the game at $f800 and use the area at $f800-$fbff for
your game.
