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?

Note that the 'version byte' is different from the private key prefix. en.bitcoin.it/wiki/List_of_address_prefixes – Nick ODell Jan 9 '15 at 21:55

0x0488B21E is the extended public key prefix / version bytes (as described in BIP32) and stands for xpub. In the same manner, 0x019DA462 stands for Ltub.
For bitcoin and litecoin these codes are:
Network Extended private Version bytes Extended public Version bytes
key prefix key prefix

How do you go about calculating these values? For example for auroracoin the prefix might be Arub. – greatwitenorth Jan 10 '15 at 21:08
