Well, I'm sure I've seen this one before, so I gave it a shot on pouet.
We can strike out the 'dbra' crewname - not there!
Searching for 'genesis' as a demo name didn't produce any results for Atari.
It's not the genesys demo too.
Searching for 'dba' produced this: http://www.pouet.net/groups.php?which=4361
Can't think of anything else right now, might investigate later.
