Here is a list of MM1 custom mansions, that have been converted for the HD version of the game.  Windows users please note that these are the custom mansions that you can play.  You cannot play the old format mansions.
All mansions in this list have been tested and should work in the HD. If not please let us know at the appropriate board in this category.

The mansions uploaded here are:
1. Those that work in the HD without any complications (as far as we could tell).  We did not have to make any changes before uploading them.
2. Those that needed minor changes to work, but without affecting the playing value of the mansion as intended by the author.  If this was the case we contacted the authors for their approval or asked them to make the necessary changes.

Other mansion, which need more reconstruction to work in the HD (as those with custom graphics) are not converted and uploaded until the authors have fixed them.

Note that the links in the list take you to the same post where the original mansion file resides.  You will note that there are now two separate files to download.  The one with the HD ready cm has "HD" included in its name.
