I have a 400mhz It has 256mb of ram it runs very well with 128 but Neogeo games load faster with 256. I'm running an Nlited version of XP I made myself. It has just about everything stripped out more than the so called tinyxp version.
http://forum.arcadecontrols.com/index.php?topic=59373.120 One big problem with tiny xp is that alot of drivers have been removed.
I can run just about every game at full speed with no frameskip. You just need to know what emus to use.
CPS1 and CPS2 =Nebula
Winkawaks= Neogeo
Modeler= System 32
Raine= Everything
Mame37b16= that's left
You should be able to run most games full speed with that setup. But it would be better if you used the command line version of mame. Specifically Fastmame. Which is a optimized version.
