about mame

[Sérgio Basto]

Hi, so if I do :

yum list \*mame\*

Installed Packages
gmameui.x86_64                0.2.10-1.fc12  @rpmfusion-nonfree                
mame.x86_64                   0.144u5-1.fc16 @rpmfusion-nonfree-updates-testing
mame-tools.x86_64             0.144u5-1.fc16 @rpmfusion-nonfree-updates-testing
qmc2-sdlmame.x86_64           0.34-1.fc16    @rpmfusion-nonfree-updates        
sdlmame-data.noarch           0144-1.fc16    @rpmfusion-nonfree-updates-testing

Available Packages
sdlmame.x86_64                0136-1.fc13    rpmfusion-nonfree                 
sdlmame-data-samples.noarch   0139-1.fc14    rpmfusion-nonfree
sdlmame-tools.x86_64          0136-1.fc13    rpmfusion-nonfree

First question : what mame-data should be installed ? 120 or 136/9 or
all or none ? 
Second sdlmame.x86_64 shouldn't be deleted ? since has been deprecated,
IIRC, and others sdl-mame-data that are obsoleted ? . 

Thanks,
