It can be quite discouraging sometimes, when nothing seems to work, so the more we are to try, the more we may find the ways to make it work, or help devs to fix issues, and be motivated by the interest the GC build receives.
You can give a try to a recent devloppement: Mission:Liftoff to begin with Theodore, for the working cores, Gambatte is kinda working too, but is ugly and not fully compatible. Theodore has an autoload function, pressing start once or twice run the chosen game (.fd, .k7 are accepted, both binary and Basic programs).

Testing pace is slow since I have to cope both with kid's school at home and hometasks while my GF is working fulltime.
I'm French, and few members are too.
