you're talking about sets, not roms.
Sets can be enabled/disabled in Scanner->Scan Results->Set Information (button bottom left)
Single roms of a set can only be removed on datfile level.
lol sorry me confusion but yeah i always made a lot of confusion on my head when i need to to distinguish this....
so if i want to disable these singles roms from scanning i can made a copy of current dat (0.241) and modify that deleting that entries ?
is it simple to do this? I need to obtain the xml from official mame.exe or i can modify the dat actually i have on my clrmamepro ? if so, where do I locate it ? I have tryed to look inside datfile and there's a file called mame.dat but it's not the file i need.
Inside cache folder i have two files.. one it's about 60MB but i can't edit whit notepad++.......
*EDIT*
apparently clrmamepro has a similar function... but you get exactly the opposite of what I would like to do.
I try this:
1 - I have saved this 7 roms name in a text file called toexclude.txt
2 - Open "Set Information" from Scanner and use the function "From File"
When i click on LOAD this specific 7 roms are be selected correctly
But apparently there's no way to do the "reverse operation" for example when after you use "Select All" and deselect some roms from same file.
I have tryed to:
1- Use "Select All"
2- Use "From File" and click "Unload"... no work ...
