When I have a good running system, is it then needless to update it (I know: “Never update a running system”… :) ).
But maybe there are a lot of bug fixes?
So maybe if I update the system, will then the DAT-files (for example for Mame) change and is there the risk, that a lot of games then will not run anymore, because of a changed dat-file/rom-set-needed?
