[Several roms inside zip file, how to pick one]

I'm setting up Launchbox, and I've just noticed that the games that I imported are zip files which contain several roms inside, and when I launch a game it seems a random rom is picked within those, how do I set it up so that a certain rom is picked within the zip files so that the actual good "!" rom is picked, is that possible or do I then have to import single rom files... I hope my question is clear, thanks.

[Dualshock 4 not working]

What's up! My dualshock4 is not working via bluetooth on Launchbox, so I was wondering if buying Big Box will be enough, I've read that it comes with added controller functionality.

If so please let me know and I can buy Big Box, or how do I fix this issue.

Thanks,
