Emulating the chips as accurate as possible means also emulate their timing and speed. And that's the problem with some games. Some chips are underdimensioned(?) for the games they have to run, resulting in slowdowns already in the Arcades. The speed of the chips is emulated properly, that's why the games are slowing down as in the Arcades because the timing and speed is exactly the same in MAME.
Sounds logical. Annoying none the less
