Using the official Adobe Standalone Flash Player (Projector Debugger) as the "emulator" has worked for me to get Flash games playable outside of Launchbox without a browser by simply double-clicking. Of course, it's not in Launchbox this way, but it works just as well with the plugin. https://www.bannersnack.com/blog/download-swf-player/
Setting up automatic controller profile associations for each flash game will be my next trick. I'm thinking maybe Retroarch might handle it if I could finagle the player in among the supported cores, but I don't see any guides for setting up custom cores. Any tips would be appreciated.
