@LiquidDivide I am glad that I could help. Thanks for pointing out the differences, especially the point with the non-retropie devices and that nothing has been done on the other script for 2 years. This should make your script much more interesting. Do you plan to include a save state selector as well?
Yes and no. If something works well, there's not really a need to keep changing and updating it. The other script does still work well and I had minimal issues with getting it working again, though I added a few changes from one of the other forks as well. I'm happy with it for now, but if this script gets more features, more robust, I'll happily switch.
