I would really like to get my hands on a zip file containing all contents of your Lightspeed folder, if you can, Drybonz.

Then I tried to make Launchbox main folder as the ROMS folder and it still worked, so I'm not sure what's going on. I tried to remove the ROMS path all together and it still worked for me. have you checked that the path for your ROM files is right? The filter didn’t work for me either until I’ve realized that the path for my ROM files was wrong.
