The more I read the 4D the more confusing it becomes, however one other thing I did notice is there is shown an amount for co - development of $25,700 not sure who this comes from:

The changes made to the incoming revenue between the 2nd Quarterly to the half yearly including the $25,700 is $219,980

Trying to take a good guess at what this is made up of 
$100,000 ZELDA (Paid in January)
US $100,000 (A $115,000) -(Not on 4c so must have also been paid in January) low as current Aussie dollar at around 72 - 74 cents
$5,700 Co development payment ($10,000 already on 4C)
Total $220,700

is the closest I can come up with, maybe someone with a bit of brains can do better
