pegasus-frontend VS skyscraper

You could try this front end. https://pegasus-frontend.org/

Have a look at pegasus-fe. Works on most OS (windows, macOS, linux, android etc.). It won't download games, but presents them in a very nice and efficient way. It also has many themes. Lastly, you can also launch programs, not only games !

Pegasus - seems like a proper launcher that can incorporate games from multiple stores? It seems promising.

Pegasus

I'm looking to create an emulation front-end (like Launchbox, Playnite, and Pegasus) using neo4j to store relationships between items (games, platforms, developers ect.). I've built myself a starting point in Java using JavaFX, but after trying to display items I'm starting to experience the limitations of that. I'm wondering if it might be a good idea for me to switch over to Unity at this point in development, before the application gets too big.

ES Desktop is great but I prefer Skyscraper for media content https://github.com/muldjord/skyscraper/tree/master

Yes, but I would suggest to make it clear on the front page / README that the project is no longer being maintained and you would encourage someone to fork it if they want to continue development. For example, like this project did:

You can try skyskraper, at least there is "Skyscraper works perfectly on macOS" in the description

This might help: Resource Cache

you might also try skyscraper, its a CLI tool for scraping folders to generate metadata for pegasus and other frontends: https://github.com/muldjord/skyscraper

It's highly configurable through the command-line interface: https://github.com/muldjord/skyscraper/blob/master/docs/CLIHELP.md

Doing this by hand would be quite tedious, of course. Lars Muldjord's Skyscraper (https://retropie.org.uk/docs/Scraper/#lars-muldjords-skyscraper) has an "import" module to cache local resources (https://github.com/muldjord/skyscraper/blob/master/docs/IMPORT.md)
