It looks like a few people have found my script. I'm glad to see it used. Hope everything goes well for you all.

@herb_fargus I have omitted the analog trigger buttons for the time being. They will likely not be used in my final build as I will be focusing on only 8 and 16 bit generation systems anyway. After this I was planning on doing a fresh RetroPie build for my Pi3 based stationary consoles. This will likely be something I have to revisit so please let me know if you are aware of any potential solutions. Thanks for the help. I appreciate it.

I got it to work.
I used these steps instead:

Works great! You can easily edit stuff in the bgmusic.py file , like startsong and add missing emulators to mute the sound for.
I stuck my Pi in a Playstation 1 case, so my Pi-station is pretty much done now:

Sorry, I purchased Raspberry Pie 3, and downloaded Retropie and have version 4.1

Everything I installed was from common search online.

I went to update something a few weeks back while tinkering and since then in the menu alone it's given the attempt to update python and then nothing

I can provide a picture if that would be helpful.

Only if the father is a really bad guy and his children are ramparts. But for all time: Peace and Harmony!
