One reason that there are different "romsets", I believe, is explained somewhere in the mame faq. Esentially each set is a different version of the game. Lets say you were Midway, and you made the rom for pacman, but you don't think the game is difficult enough. So what you do is reprogram the game a little, then make a new "set" of roms to replace the original. Thus the original is referred to as "set one", and the harder version is "set two".
A Bootleg rom is when you have a game that features some type of security encryption to keep people from copying your romset. You remove the encryption so that it can be copied. A Bootleg is usually the actual dump of a copied game.
Hope that clarifies a little.
: When I go to mame.dk to download roms, I sometimes find the name of the rom folled by 'set 1' and the same rom with 'set 2'. What are these sets? Both games are the same? And what are bootlegs? In some cases I have to download the rom but also the bootleg... weird..
