Oh? Pardon my ignorance. I was under the impression that Gold was just Classic repackaged with a bunch of mods and a new manual. But I am new to the whole series with Gold.

It can help to avoid confusion like this by bumping the major revision number when making a non-upwards compatible change in the software.

The progression from IV to V does not introduce the ambiguity that arises when going from "Classic" to "Gold". And no one would expect SEIV files to work unmodified on SEV.
