Just curious, does MAME emulate traditional games faster as new versions are released or do they slow them down? I would like to think that as the code is improved upon, that emulation would be faster for the games, but I have never asked the question. The reason I ask this is that I'm not sure if I should upgrade to 0.59 if all it does is bloat up my harddrive and add support for some "closet games" released in the early 80s. Mortal Kombat 2 (3.1) ran normal in the past, but as I have upgraded versions of MAME, it has begun to slow down. I am using 1.4GHZ AMD XP with 256MB of RAM and a GeForce 3 Ti-200 card so I know my hardware has more than enough to run it. Hell, I've been running Killer Instict 2 on this machine for the longest time with no problems at all. In fact, I've run it with all of the options set, and it has yet to stall on me. Perhaps MAME is slowing its own games down as it ages?
