I am not making new profile as I am using .dat files from progettosnaps.
Problem is I get the odd rom that the newer versions of clrmamepro skips past and reports 'missing'.
I use older versions of Clrmamepro and the roms are not skipped and added to archives.
It is only the odd few roms, but the difference is having a complete set at the end.
I suspect the roms were known as 'bad dumps' later on in Mame's life and the newer versions of Clrmamepro are not adding them to the archives where the older versions of Clrmamepro would.
I can confirm that Clrmamepro v4.00b (and probably all older versions before) will add these roms to the archives.
Clrmamepro v4.01 and all modern versions since will not add these roms to archives therefore causing 'missing roms'.
