MushroomHunter, I don't think this was working. Lightspeed should for this check dependancies.
Personally I use LightSpeed for MAMEWAH list creation based on already created custom roms directory. I'm using my own script that copies necessary files based on MAMEUI/ARCADE64 favorites list.
There are still one problem with MAMEWAH list export. Program exports at the beginning small string  that makes think MAMEWAH that first game on list in for example 005 instead of 005. Those signs (which is strange) are not visible in notepad.
Usefull option would be also removing or moving to end of line word "The" since many games have this at the beginning of it's name. Right now I have to do this manually.
