That will be fantastic. I have been enjoying Delta, and DS translates surprisingly well to iOS. Having the bottom half of the screen touch sensitive means you never have to reach too far. And the screens on the DS were not too different in size from stacking them on the phone screen. It would be really great to get Mario Kart and Tetris going online.
BaconBits was a Reddit tracker with a maximum user count around 6000. They eventually closed because most of the users could get the same content from other trackers, with better choices about bitrate or codec, or better seeding. I’m not convinced Lemmy has enough users to support a private tracker, I think you need like 20k active users to be worthwhile.
