What's the most compelling reason to move from 18.07 to 6.1? My current setup runs decent enough. I've read through the general change log. I guess if there is greater compatibility from a MAME perspective as well as other performace improvements, I would make the leap. I'm just looking from input from others here that have moved. What are you seeing? Is it worth it?
Lastly, is there a supported path from 6.0 to 6.1 that doesn't entail installing fresh?
