WOOOOOWWW, It is oveeerrr... it is done, it´s working, I can´t hardly believe it, but We managed to get it working. The problem with the new games options had to do with the locations file. I replace it with a good one, and now it is working like always did, grrreeeeat
What I did to get atmosphere working was to not delete the old atmosphere and copying the new one, but copying the new one over the old folders, and replacing what already existed. That solved the problem of the games not loading. And then, I installed hbg saying yes to the question to install the kip file, and all solved...
So I guess that the problem with the kip file of hbg was incompatibility with atmospohere 0.10.1....
Best regards, and my most sincere gratitude for all your time and help.
