I have a chance to aquire a dual rig and was wondering because mame is CPU intensive, would dual cpus help performance? Does mame or mamewah support dual cpus? Anyone out their experimented with this? I am talking dual Pentium 3 866's. Thanks all.

SirPoonga is correct. I tested this w/ test rigs of AMD 1800XP and a Dual AMD 1800MP. Systems ran nearly identical. Mame only uses on processor.
I sincerely wish someone would find a way to take advantage of the extra horsepower though.

Trouble is that they sync issues needed would take an extra processor.
I hope the seperate the parts that could be seperated without much problems.
processors + memory on one processor.
Video and input on another non-essentials.
The video memory might be a sync issue.. but shouldn't be that bad since most multi-processor systems can quickly sync memory. Plus you might get a trible buffer working on the P&M processor could fill in a specific memory location... And the only sync would be around switching between the pages...
IE, move all non-essential parts to another processor.
but take note... you wont' get any extra games running... Bottle necks for most slow games wont be effected by this...
This is more of a future... next amd and intels will problabl be multiprocessors.

if your hyperthreading your as close to multiprocessing as your going to get with mame.
my 3.4ghz extreme shows as two processors and all my system info indicates that i am running a multiprocessor setup.
