xp for games only and to run in ram after boot from cd

I have a MSI K9N sli platinum nvidia 570 with a amd 4500+ and 2g of ram, I use linux and I am trying to make a copy of xp to run from cd and to be less than 200mb and its only purpose is to run games so how far can I strip xp, I know how to use nlite but a year ago I went through 25 blank cds to get one that would install on my sata hard drive so I want some opinions on this before I go again and destroy cds, I know of bartPE its not what I am looking for it has to see my sata that's where games are going to be installed on a fat partition and its not as light as want it
