Sure it's possible...well...if you understand what usually "updating" means, you see why downgrading is a bit more complex.
An update includes:
- reorganization of sets (place change, parent/clone behaviour)
- renames of files
- new additions of files
- ...
- removal or replacement of bad dumps ...and there you go...of course if you downgrade you need to find such replaced files again.
So you simply load an old dat/mame in your profiler and rebuild your 'new' set to an old one....everything missing then did simply change in the past (bad dumps replaced with new ones or complete removals)....so find such old files and you're done.
Personally I think there is no reason to downgrade anyway....but...it's your choice...
