Another one I remember with great fondness is, Jose's (I believe that was how it was spelled).
Used to wait at night for the next mame release then the next day at work, at lunch I'd be on the shop computer downloading all the rooms I could in 45 minutes then get home and finish downloading any that were left on the list.
Always kept a backup folder of the newest release and "sooner" roms on the shop computer just in case.
