I thought about that when writing the parser. The callbacks are
only called when there is no error in the ini file, and then are always
called in order:
gameid, name, manufacturer, year, author,
rom, banksize, initial, register
You can check this with the binary present in the pack. Try to
place the banksize statement in the end of the file, and see how it's
printed in correct order at output.

I don't think so, this problem does not exist if you use
a context-sensitive parser. We always know that after a "Name" tag the
contents of the array must be a two-digit, lowercase, iso639 language
code; and we always know that after a "Register" tag there must be an
address/mask pair.

I was sleepy when I wrote the header files :)
Of course LGPL would be much better, with LGPL you can add it to
fmsx without worries, but all changes in the parser itself must be
released with source. I think it's fair, this way we're always improving
the parser.

You're right. My goal is not to make everyone open sources,
instead I want everyone using the unified format.
