While I'm not familiar with the legal cases you refer to, I'm willing to accept in principle that in this hypothetical case you could have some sort of copyright over the changes to the code. However, you wouldn't have copyright to the final code itself if it was too bound up with the original code to separate your contributions and you didn't have authorization to modify it as you did.

I'm not sure exactly what it means legally to put your name at the top of a MAME source code file as a copyright holder, but I wouldn't have thought of it as referring solely to some set of changes that couldn't even be described simply by looking at the file itself. If MAMEdev wants to relicense code that Haze contributed to, perhaps they can come up with a statement he would be comfortable making. For example:

"I hereby authorize MAME developers to relicense any changes to the MAME source code over which I own copyright as [GPL/BSD/etc.], provided that they first audit the files incorporating those changes to ensure that the relicensing does not violate any licenses or copyright."
