Thanks for quick reply.
I had some experience with standard mess build, but obviously its not enough here.
I just cant figured out, whats I am doing wrong.
Found this tutorial here https://www.youtube.com/watch?v=Kq04IoKdbRA, tryin online updater in retroarch menu, he update all stuff and put some of this in home/pi/.configs, but cant find mess core or start it, even if I manually select them in retroarch menu.
It takes me long time to compile and feeling preety much frustrating about this.
I also found this small tutorial, but still no luck to start libretro mess:
Any help about make this work is welcomed.
