Yeah, I got it! :D
Three points:
1.:’subprocess’ does not work. I had to use ‘os.system’
2.: I had to use the full path, when calling the ‘retroarch’ command.
3.: I had to insert a backslash for each space and parentheses in the name of the roms.
The rest should be simple, but we will see…
Again, thanks for the help!
