There's plenty of them out there but none of them do what I would like them to do.

Most of them crash when opening a file or simply corrupt the data. Many don't run at all. It seems to me that most were written 3-4 years ago for AS2 .sols and no longer work with FP9/AS3 sols. I'd attempt to write my own using AIR but I can't find a new spec of the byte format.

There's an explanation of the file format here: http://sourceforge.net/docman/display_doc.php?docid=27026&group_id=131628

and another here: http://sourceforge.net/docman/display_doc.php?docid=27026&group_id=131628

but it looks as though both of these docs are a good 4 years old (pre-FP9) and as I'm not skilled or experienced in file formats, writing a new one, especially without an updated spec, is seeming like less and less of a viable option.

Ideally I'd like one that can not only read the .sol, but edit and save new values also.

Thanks!
