Raspberry Pi 2 with Mame - anyone tried it yet?

Mame isn't going to use the other cores, so what you are left with is a 20 percent increase in clock speed. It struggled terribly before and I don't think a 20 percent increase in clock speed will help very much.

According to this benchmark of just a single core:
http://www.tenpencepiece.net/blog/2015/02/08/benchmarking-the-original-raspberry-pi-model-b/
The rpi2 is 1.8 times faster than a rpi1.
what that turns into in terms of emulation on one core i don't know yet until I get it compiled and installed.
However, advmame on linux x86 uses a 2nd core for the rescale affects so there could be a performance boost there.
Saneless:
I don't have any experience with the old Pi but things seemed pretty good for me.
I'm not sure which version of advmame RetroPie 2.6 uses but it's a bit screwy. Can't get good sound in Donkey Kong.
It also seemed to struggle a little when I set everything to be vertical but it got better when I limited the resolution to 640x480.
Only real problem is how damn awful this 17" LCD looks compared to my 27" CRT. The Pi MAMEs don't seem to have any video options either.
nitrogen_widget:
Looks like they are using .9 something version of advmame.
I remember they used this on the rpi1 so you could play star wars.
Try turning on the scan lines in advmame.
Makes it look a little better.
Anyway, mortal kombat runs at about 60%. Haha.
That's like a 55% increase from the first RPI.
But games that gave me issues before like gyruss and ghouls and ghosts run great now on advmame.
Aceisback:
Just replaced my Pi 1 B+ with the Pi 2 and had some better performance than the before, but that could be due to the Retropie image I used also. Regardless, I am quite pleased with the performance of my setup.
paigeoliver:
I stand corrected. I was not aware the new processor was also more efficient per clock.

Several benchmarks I've seen suggest that single core performance is about 2.5 times the speed of the previous version of the Pi.
That sounds about right to me as the ARMv7 processor is known to be about twice the speed of the previous generation of ARM processor (assuming an equivalent clock speed).
