Romcenter

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

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

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

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.

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

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