Honestly I think it would be easier to find rompacks with more seeders, Download batocera and then add your Roms yourself. It's not that much more work although it might feel like it
Damn shit like this freaks me out I wonder how easy I would be to track down
No worries, gotta share the booty!
I personally use adguard to block connections whilst also doubling up as ad/tracker blocker. You can also route different apps through a proxy network such as tor if you want certain apps to be more private
Mobilism is good for games/apps. Most of the apks have trackers removed and have access to paid content. If you're particularly concerned you could block them with a firewall
If you don't get an answer here might be worth trying mobilism forum. That's where I get a my apks
I sort of regretted downloading massive rom packs for retro consoles because I never actually get round to playing them. it's so hard to settle on one when there's so much choice. But now with the recent crack downs on ROM sites I'm really glad I've preserved them. Hoard away friend!
