I have some questions about organizing MameUI
for initial setup or updating it.
My first question is regarding Play Time,
which is shown in one of the Columns in MameUI.
But every time after upgrading MameUI to a newer version,
I don't know how to migrate this data.
Where is this information stored.
How do I migrate them to another MameUI installation.
I have tried to migrate both the folders sta and nvram.
They seem to contain data but not the Play Time.
Thank you for any help and information.
