How to hide MAME Bios, but still make them functional?

[floattube]

I use an emulator front end for MAME. The only complaint I have is in my list of games, the bios show up. There is no way to hide them in the front end, so I was wondering if there was a way to hide them or put them in a new directory so they don't display in my games, but function.

TL;DR: I want to hide MAME bios.

THIS. Just use the Mame32/UI front end. It has so many list options including year, manufacturer, controller and genre.
