Missing file endings

I compared seven different mus-files. When I save them using "Save As" instead
of "Save", I notice the following differences:

1) Byte 0x3E is changed from 0x01 to 0x00. This happens with all test files.

2) On some of the files there couple of other changed bytes.

3) The "Save As" -version is missing 96 bytes from the end.

When I add the missing 96 bytes to the end of the file, the file opens
correctly. Other changes can remain as they are.

Five of the seven files have the same missing tail (4pctmp-tail-unique.bin,
johnny-tail-unique.bin, pvoctmp-tail-unique.bin, silent-tail-unique.bin and
somestuff-tail-unique.bin). Sixth one's (rore2-tail.bin) 13th byte is different
than the one in the first five files (0x02 instead of 0x03). Seventh one
(lupo-tail.bin) has the same first 9 bytes as the first, but then bytes 10 to
13 and 16 to 24 are different. The rest of the tails are the same with all the
files.

I'll attach the missing tails and their differences to this comment.

Does anyone have suggestions on how to proceed with this information? I mean,
does this help? I would like to get this program to work correctly with wine. I
am willing to do the work needed (I even have little programming experience),
but I don't know how to proceed solving this.
