Error importing a MAME FULL SET

[famofeemily]

Hi, first I apologize for my bad English.

I can't use the tool to import a MAME Full Set:

1.- I have a test folder with 3 ROMs for MAME 0.241 that work perfectly in that version of MAME but I also tested them in version 0.249. I've also tried dozens of other ROMs with the same result so I don't think the ROM files are the problem:

Not quite understanding the issue. 

You mention the tool to import Mame full set. However, you mention you issue is roms not working in different Mame versions. 

Is your issue importing in to LB or playing games in a different version of Mame you downloaded?

If it is playing the games in the different Mame then you need to make sure the new Mame knows where your roms are located.
