Currently it’s only available currently on the Amazon app store and costs around $5. RetroGamesCorp has a guide for installing and setting it up for those interested.
For those that have tried it out, do you happen to know if it lists whether achievements are available with a trophy icon like AmberELEC does?
The videos I’ve seen haven’t shown it.
Edit: The app is longer available on the Amazon app store. They have shifted to Patreon. I made a follow up post about it with their explanation which can be found here in !sbcgaming@lemmy.ml
Thanks for the update. I made a new post about it in this community and added my thoughts about it if you want to discuss it
