It's working for me now as well, thank you.

@quicksilver will do, thanks!

@melbmatt50 Again, the package has not been removed from RetroPie, it's still in the optional packages section.

@edmaul69 @gpmcty I tried editing the config file as the website stated, but still can't get it to work. When you say hack file, do you mean the one the listed (the config file edited)?
I can't get vision-dapter to work at all. It is identified, but I get the message 'Not Configured'.
Any ideas what I might be doing wrong?
