> Would it be possible to compress the merged dats in memory?

well...on my list is a reduce-database-memory item for a long time....since I didn't care that much about resources (and MAME is still rather small) I didn't touch it. Of course there are several possible methods to reduce the memusage...(e.g. by not keeping the full db in memory...or reducing / compressing the data) but of course this has an impact on scanning/rebuilding speed.
