Consolidate ROMs not working as expected.

[Burpy]

Version 7.7 - Released February 14, 2017

New Feature: A new "Consolidate ROMs" option is available under the Tools menu in LaunchBox to combine ROMs for existing collections, just like import

Tested on Windows 10 Pro 1809, LaunchBox v9.9

I imported a complete set of SNES ROMs (many versions) using the import feature and it didn't do a good job.
For example, after importing, some games ended like this one:

see bug1,jpg and bug2.jpg

• Actraiser 2 (Europe) (En,Fr,De) as main rom

  • Actraiser 2 (Europe) (En,Fr,De)
  • ActRaiser 2 - Chinmoku e no Seisen (Japan)

• ActRaiser 2 (USA) as main rom

  • Actraiser 2 (Europe) (En,Fr,De)
  • ActRaiser 2 (USA)

If I use "Consolidate ROMs" option afterwards it duplicates the versions on the additional applications:

see bug3,jpg

• ActRaiser 2 (USA) as main rom

  • Actraiser 2 (Europe) (En,Fr,De)
  • Actraiser 2 (Europe) (En,Fr,De)
  • ActRaiser 2 - Chinmoku e no Seisen (Japan)
  • ActRaiser 2 (USA)

Other examples: Blackthorne, Garry Kitchen's Super Battletank: War in the Gulf, Out of This World, etc.
Note that these duplicates have the same file name. Also note that this test was done with a complete set of aprox 3500 files. Doing it only with the rooms indicate won’t reproduce the bug.

So I deleted and tried again importing it as individual roms. Then I used the "Consolidate ROMs" option. It didn't do the job as well. And if I do it more than once there’s a chance that many versions get deleted.

For example, Final Fantasy Mystic Quest:

Import individual:

• Mystic Quest Legend (Europe)
• Mystic Quest Legend (Germany)
• Mystic Quest Legend (France)
• Final Fantasy USA - Mystic Quest (Japan)
• Final Fantasy - Mystic Quest (USA) (Rev 1)
• Final Fantasy - Mystic Quest (USA)

First pass, see bug4,jpg

• Mystic Quest Legend (Europe)

  • Mystic Quest Legend (Europe)

• Mystic Quest Legend (Germany)

  • Mystic Quest Legend (Germany)

• Mystic Quest Legend (France)

  • Mystic Quest Legend (France)

• Final Fantasy - Mystic Quest (USA) (Rev 1)

  • Final Fantasy USA - Mystic Quest (Japan)
  • Final Fantasy - Mystic Quest (USA) (Rev 1)

• Final Fantasy - Mystic Quest (USA)

  • Final Fantasy - Mystic Quest (USA)

Second pass, see bug5,jpg

• Final Fantasy - Mystic Quest (USA) as main rom

  • Final Fantasy USA - Mystic Quest (Japan)
  • Final Fantasy - Mystic Quest (USA) (Rev 1)
  • Final Fantasy - Mystic Quest (USA)

Also, in many times, the beta version of the game was prioritized over the official version.

Note that the last test was done with 3500 files. Doing it with the roms indicated will reproduce the same result as the first pass, but the second pass will not delete the roms. It will successfully merge them.
