Romcenter

I don't, I have just one. I will start fresh to be sure. Thanks for your attention.

Maybe you have several datafiles open in romcenter and try to move from one to another ?

I did the BT already, thanks. I think I found another bug. When I select filtered roms to copy to another place a message saying DB os already opened by some other windows process is show and program crash.

Should be a bug. I will have a look for next release.
Can you create a bug report?

Please, is it really a bug or I misunderstood it?

I'm trying to manage my Retropie FBA Rom. Some ROMs have region on title, some didn't have any region info.

If I do like this, everything works as expected:

BR
US
EU
WORLD

But if I try to add NONE to the very ending, expecting to add those regionless ROMs to the database I end up with various ROM versions to the same game. 1 game 1 rom fail as if NONE (no region) was meaning ALL (all regions + NONE). Can you confirm this behavior?

Thanks in advance, keep your good work
