Pick a sire and a dam - from the ROM roster, your own stable, or the community Studbook - and see what that pairing gives under the foal rules of the machine you make the card for, decoded from its ROM: the dam counts as the first parent, internals and bands average down, dirt averages each half, coats follow the hidden genes, and DOC '99 uses its own routine (no rare band). A few things live only inside a cabinet, such as the counter that decides special coats, so for those the Lab uses the long-run odds.
