Were you able to get them to work with animal map? because currently as far as I know it is impossible, I use my old G6 as a bridge to edit save files.
I feel like school, back when I was actually in school, was more entertaining though, because of how much I get to interact with people, hang out with friends, and other stuff like that. All I get to talk to at work is my boring coworkers lol
