There are plenty of pretty good controllers to buy. I recommend something with a real stick, just like in the old arcade. I've wasted a lot of money buying gamepads over the years and not even the recent NES30 pads are good enough to play R-Type and my other favorites with precision. I recently got a HORI Real Arcade Pro and it's excellent. The other thing that makes MAME feel off is the screen. 27" iMac may be a very good screen, but it's not a good CRT with the glowing pixels of the past.
