As mentioned...it is easy even if you don't see that on the first look. Updating from 1 MAME version to another is just "load the mame profiler in the profiler, enter the scanner, hit scan". Yes, of course you need to do a one-time setup where you 1) setup rompath in settings and 2) toggle the fix options in the scanner. That's basically it.
The default options are set to values which are fine for any standard mame user. You got tooltips for each option and usually they are self explaining -if you know the standard mame terms like "merging"-. I mean what do you expect from a "check name" or a "fix name" option...
And everybody is welcomed to bring in ideas for the layout of options on the cmpro board. Actually I ask about layout changes every now and then there and all replying users say the same: keep it as it is...
Yes...I need to update the docs...and I will do so if I got time.... and if it's too complex for you, simply use a different tool or write your own one. I already did remove several options which are hardly used/toggled in the past. Scanner Advanced Options became very small lately... Yes, it might be more a 199x layout and not some fancy 2012 web / metro layout...but I actually don't care that much ... not to mention the needed time for a change which I don't have.
