XBOX360 and XBOX games

You know, I am consistently (and pleasantly) surprised at the compatibility of old XBOX games on the on the XBOX360. When you consider that the games are running and emulation (the platforms are completely different), the speed difference between the two is difficult to discern. It is also interesting to see which games look as good when viewed at the higher res. Black, for example, looks just as good on my 20″ LCD panel and the XBOX360 at more than twice the resolution than it did on the XBOX. Far Cry, however, looks particularly pixellated at times. The only time I use the original XBOX now is when playing Dancing Stage Unleashed where the screen and mat are easier to use together.
