I threw the emulator on a computer with roughly the same specs just for kicks, and yeah, it sucked... but there are a couple games that will actually run at almost full speed on it. Stuff like Dragon Quest 8, the various Gust games (At tonelico, Ateler Iris, Mana Khamenia), and I think I tried one of the Disgaea games with mostly successful results.
But yeah, other than that you are pretty much looking at no joy without a much beefier CPU.
