I have certain files with double file extensions. In my case, my gamecube and wii games have the extension .iso.dec. This is for the special decompression program, it keeps the .iso in the filename to preserve its original filetype.
Launchbox doesn't quite handle the double-extension very well. When importing the roms, it recognizes a lot of games, but it also doesn't recognize a lot of games. This is probably due to the fact that it actually includes .iso in the game title (it shows as such in the unrecognized games). Because of that, it also doesn't properly merge a lot of games with the same title. A lot of games have the same title for the European and the US release, but it oftentimes does recognize the US release, but then doesn't merge it with the other releases (probably because the title is different after it removed the .iso from the US 'title').
It seems like an easy fix to me. Either cut the title until the first dot in the filename instead of the last one. Or if that's not save enough, just check for double file extensions. I mean, three or more file extensions seems pretty ridiculous to me, I don't think that'll ever happen.
Nevertheless, it's quite annoying because I can't properly import my roms (at least not without a ton of manual work).
