Mine… My Xbox 360 slim only costed 129 euro back in 2012 and to this day still work like brand new, you would think that the disc drive would stop working but no. Never had the need of open it or clean it’s insides. Still great, I just don’t use it anymore since I feel it’s outdated and loading speeds are better nowadays.
Admittedly it’s a bit of manual tech fiddling involved, but you can accomplish this by using network shares and some careful scripting. For example, I’ve got both my desktop and steamdeck with a launch script configured in Lutris on both. The script symlinks a network share path to the appropriate save game location for each game before running the game. Granted you have to figure out where each game wants it’s save to be stored, but that’s not too difficult once you get used to it.
Fiddly and nerdy for sure, and not for the non technical, but it’s pretty nice, I’ve found! Would be even better if there was some more automated solution though.
