<p>I'm looking at creating a deterministic wallet for some of the less popular altcoins. Bitcoin has a magic byte of '0488b21e' and litecoin '019da462'. How are these determined or calculated? Also how would I generate these values for other altcoins?</p>

Note that the 'version byte' is different from the private key prefix. https://en.bitcoin.it/wiki/List_of_address_prefixes
