Hey, when I wrote MEAGRE, there was nothing else like it out there. I know it's not the best looking front end but it gets the job done. I wish it looked as good as LaunchBox!
I would love it if LaunchBox imported the information from the ExoDOS collection in MEAGRE. It would actually be a fairly simple process initially of scanning each folder for the .ini file or for the meagre folder itself (each game has a meagre folder). This parent folder can then be used as the application location, the game can be set to use DOSBox of course, and the custom .conf file is always going to be called dosbox.conf and reside in the parent folder.
The other meta data can then be brought in from an online database or used from the various image and documentation folders in the meagre directory for each game.
I know MEAGRE and ExoDOS are probably too "small market" to add as a major import function of LaunchBox but it would be cool. Just to be clear, I only wrote MEAGRE. Although I'm fairly versed in the ExoDOS data and formats, all of that data was compiled by EXO, a different guy.
