OK, so this might be a pretty straight forward question, but I am not entirely sure.
Currently I have an 1xxx-in-1 jamma board connected to a VGA monitor. To be honest, the quality of the visuals hooked up to the monitor are not great (trust me it is not the monitors fault). Obviously the refresh rate and resolution are much different than a normal arcade monitor.
I have like 5 dreamcasts, so I thought it might be a cool project to gut two controllers (would get these:

Would be great to actually be able to play MvC2 and other Sega Dreamcast arcade games on there.
Here is a pic of what I am working with, just a generic cab:

What do you think?
