Scofield Friend, if you can do the complete draStic installation in batocera and get to play some game like "New Super Mario bross" could you create an easy-to-understand tutorial for lay people, like me, to install it?
I work with computers, but I am a layman in linux and how to do these processes ... so only a very complete tutorial could help me and others install this DraStic emulator in the batocera.
As it could be seen on youTube, the r2.0.5.3 version of this emulator is fully streamed on the hardware of RaspBerry Pi 3, but since this is a closed emulator and not a core of the booklet, I believe only experienced users like you Success by adding it annually, and if they succeed and want to help us, they can create a tutorial for us on a topic of their own ...
