This constant arguement never ceases to amaze me. Sure Mame .86 might run neo geo faster than .85, but I promise you that .55 smokes them both. I'll run a quick test on my laptop.

--- End quote ---

The point was that not all versions of mame are slower than the previous version.
How much slower is mame 56 than 55?
I don't disagree that older versions of mame run games faster (if sometimes less accurately).

But I disagree that "each new one is generally slower than the last". This is true sometimes but not "generally".
 
And the explanation for the slowdowns is usually improved emulation. (better graphics, better sound, etc).  Or changes to the mame core (this usually affects all games) made to extend the functionality of mame.





paigeoliver:
The slowdowns are better explained this way.

Mame .55 probably already had Nam 1975 emulated perfectly. But there was another Neo Geo game or another game using the same processor/soundchip/monkeymagicinput chip that didn't properly work using the existing core, so existing emulation core for that processor/soundchip/monkeymagicinputchip had to be made more complex to support THAT game and thus slows down the old game.

Chris:
Also, vectors got a lot slower in later versions due to alpha blending.

paigeoliver:
There are of course SOME anomolies

Hustle

Mame .55 ----- 164 fps

mame .65 ----- 681 fps

Mame .86 ----- 533 fps

In the case of hustle the changes appear to be driver specific, as it displays different warning messages in each version, and changes to a different color in the current version.

goofy:
Is ArcadeOS just a MAME frontend similar to MAME32 or is it actually a different emulator?

Also, any suggested operating system I should run? Win98 or XP?
