I have testing the compatibily with some single players maps created by the community (campaing and multiplayers maps with IA, you know crazy floods everywhere) and works fine, not perfectly but is good enough,
You make me really happy with this, and if in the future you allow people to have unlimeted maps of halo custom edition instead of replacing and we able to play online in a future custom game browser, well that will be AMAZING.

But i am happy, at least halo custom edition content wont be forgiven thx to mcc compatibility.

Good job 343.
