So I finally downloaded the last of the N64 ROMs as cataloged in the GoodN64 DAT file. There are about 27 gigabytes of them! It took me over a month of constantly leeching flies from my favorite ROM fileserver to get it all. And they fill up five and a half DVDs. I'm really perplexed as to why Cowering includes bad dumps and overdumps in his DAT files. If I get rid of these files (which will never work in any emulator), it cuts down on the file bloat by over 10 GB!! Perhaps I'll start publishing my own variants of the Good DATs which have no -o or -b ROMs.
