If version info is not present in rom file name, game title is used as version info.

[Tom W]

If version info is not present in rom file name, game title is used as version info. This results in game names showing twice in LB. You can bulk remove the invalid version info for entire platforms, but this becomes messy and laborious if a platform contains roms with file names containing bot version info and no version info.
