Thanks @BuZz! I had forgotten about the addSystem option. I'll have to test that out. Thanks for considering platforms.cfg too.
@BuZz - Boom. That did it. Thanks!
@mitu Thank you very much for the clarification!
@mitu That was a brilliant solution to use .zip! :)
One problem less, many many thanks!
V2 of my toolkit may help you out. I have a script to do this exact thing.
If you take a look at my channel (in my sig) the legacy (old) version of my retropie toolkit will also do this for you.
Hope this helps!
