Unless you're using the AdvanceMame emulator to generate PNGs you can skip the advpng line. https://linux.die.net/man/1/advpng

Basically ensures that all of your files are optimized the same way.

Yes that was the case, nevertheless as things move forward, if there's a better way to tweak this script, I'm open to update it. Let me know what needs to be updated, and I'll do accordingly :)

Thanks to everyone coming here and saying hi, I appreciate any feedback and I'm glad you find this useful. Most of the time I do create gists for myself as a reminder for the future, but I'm glad others find it useful too.

You could just pop it in a regular repo and allow pull requests. Thanks for the scripts, BTW: very helpful.
