I modded several PS3s back in 2019-2020 and flipped a few on eBay before they cracked down. I really enjoyed taking them apart, cleaning, putting new thermal paste on, etc. Never successfully delidded one, that was always the ultimate challenge in my mind. The last one I did was a gift for my son-in-law back in 2022 ish. I had always loaded games the standard ftp routes, etc. but the one i prepped for him, I experimented with the app linked below - on the playstation 3 itself and it was phenomenal… direct download and install directly from the PS3 itself. Including games, addons, etc.

works great on ATV tvos. Worth the $10 for the pro version which allows real-debrid Api key use connected to streamio and other sources… pair with infuse pro and your ATV will be set

Telegram groups are where I’ve seen the most. Another guy just posted multiple IPA repositories yesterday in /r sideloaded. Search for his post entitled, “Repos for Feather”
