Unrecognized code in fmp12 file

[sonovice]

Hi,

Thank you for your great tools. I am trying to dump the content of an fmp12 file made with FileMaker Pro 7.0. Unfortunately, fmpdump exits with the following msg:
(I have uncommented the additional debug output lines mentioned in #3)

Is there anything I can do about this?

EDIT:
Dump of block 2 can be found here: https://gist.github.com/sonovice/6902dc351daa8b938c02d2459ceb9db8

EDIT2:
An important information might be that the dataset consists of actually 3 fmp12 files that are somehow linked.
