A Few Xbox 360 Backwards Compatibility Questions

Does Halo 1 and 2 work perfectly on the Xbox 360? Also, how well does Conker: Live and Reloaded work on the 360?

When you reach the site, ctrl+f then type the name of your game

Remember, you need a HDD to play any compatible Xbox game

No more Live for original Xbox games anymore. That includes Halo 2, which I never got to play :(

Out of the games you listed, I've only played Halo on the 360 and it seems to work fine.
