it includes 7 additional technologies (Impact, MPS2, SYS1, Scorpion 1, Scorpion 2, SYS80 and SYS5) and will therefore allow alot of older machines to be emulated.
it also allows certain layouts that did not function correctly in mfme 1.1 to work (mad house for example).
i hope that clears things up abit.
