I had a lot of duplicate MS-DOS games, and when I tried to use the "Consolidate roms for MS-DOS" tool, it would just say "The selected platform is not an emulated ROM-based platform." But I had so many duplicates that not consolidating them was not an option. So I wrote a script that imitates what the tool did for my PlayStation library.

It seemed to work for me; now I only see one entry per game and I have the option of "additional apps" for the others.

Usage instructions:

- Download Python: https://www.python.org/downloads/
- Double click on the script or run it via command line `python path/to/file`
- Enter a full path to the platform you wish to consolidate 
  - Note: the platform should not have been consolidated already (i.e., it should have no additional apps for any game)
  - Platform XML files are located at LaunchBox\Data\Platforms
- Script will generate a file called {file name}-consolidated; backup your previous XML file and then rename the new file to take its place
- Make sure to remove all other XML files for the newly consolidated platform from the Data\Platforms folder or Launchbox may use one of those old/undesired files

Here is the original question I asked on the forums about solving this:
