If you are starting from a fresh 3.0 install, you need to update your setup script and do a full binary install for the n64 plugins to work properly. they also have separate configuration files that are outlined in the videos linked on the wiki page.
For Minecraft- same method as above- update setup script, except you’ll install from experimental. Obviously you’ll need a mouse and a keyboard and you’ll need to use your keyboard to navigate the menu. Buzz just fixed the screen resolution issue and the exit issue (once you are in a world you can use the mouse to exit out of the window.) as it stands without the update, the only way to exit is to reboot from SSH. I’ve been working on adding experimental Builds to the Wiki and I was hoping to get to minecraft today.
**Edit: Minecraft has been added to the wiki
