; CERES SPECIFIC RAM

$7E2000 - set to 1 when Ridley starts flying $A4BD
$7E2002 - init to 1, read by tail fling trigger routine to skip, zeroed during swoops (Ceres only). Maybe used to sync next tail fling with the swoop
$7E2004 - tail fling trigger
$7E200C - 
$7E200E - Y acceleration
$7E201E - init to 0, tail swing delay (7-16h) when compared to $2022, set to 8 by $BBF1 Drop Samus, set to B by $B5C4 Consider tailbouncing, set to $10 by $B68B


$7E7800 - counter/timer
