I knew how to FIND the first 4 characters, but I didn't know what it consisted of.

This is the part I didn't know about.
Can you be more specific on what entails the header(s) that are being hashed? I'd like to be able to calculate it myself should I find a need. If it's a complex process to do by hand then I guess I'm stuck using existing applications. If it's a single area that's easily located (or perhaps always in the same spot!) then I'd like to know (my hex editor can do CRC32s of specific regions).
Interestingly enough, doing a CRC32 of an entire game in particular yields a checksum with the top 16 bits equal to the bottom 16. This in tandem with the fact that the checksum I got didn't match the one my Action Replay Code Manager was displaying gave me a surprise.
