I just read a thread on filefront about playing SFC on netbooks. Unfortunately the thread author have a pirated XP. So I would like to provide my experience here.
When discussing about netbooks, actually most of them share same hardware specs. Since the VGA is most important part of playing games, I will make a simple classification below:
1)Most netbooks you can find on the market, have Intel Integrate Graphic chipsets(915 or 945).
2)As far as I know, few of them have nVidia VGA inside, e.g. Asus n10j(nVidia 9300), HP 311(nVidia "ION").
3)I own a HP 2133 which has a VIA Chrome9 IGP.
When it comes to the HP 2133 series, many will argue that the VIA C7-M processor and IGP lack proformance for a modern machine. However, I can play SFC1/2/OP/3 on it just fine. I can even run gmax on it. But that's only my experience.
I think the netbooks which have nVidia should run games without problem. So if any one want to share your thoughts, feel free to reply.
