Wired Internet would help to fix the Cloud issue. I can reliably play XCloud games on PC, Series X, and Mobile on my WiFi 6 connection, and even on 5G with my phone, but YMMV.
Skiptrace
The Lodge Basement has an Infinite Mass Storage Unit.
I'm loving the game for it being finally a Bethesda game in a setting I actually enjoy.
And, No Man's Sky tickles a completely different itch for me.
The setting is actually really cool. New Atlantis is actually quite utopian looking. I haven't gotten too deep into the game yet, only about 3 hours so far.
Even with a forwarder???
It's an engine limitation. The Engine that Bethesda holds onto with an iron fist is what hampers their games.
However, the opposite side of the coin is, that it makes them super easy to modify, so people can make their own additions. Because Starfield is using the same engine as Skyrim and Fallout 4.
I honestly do not know if he ships to Germany. At worst you can use a shipping forwarding service.
I wouldn't recommend Aliexpress TBH. I highly recommend Elite Obsolete, he sells iPod parts new and old stock (Cases, Motherboards, iFlash Kits, etc.) he even sells fully made pods.
You should be able to put a 3000mAh battery in a 5th/6th/7th Generation iPod as long as you get an iFlash board and a Thick Backplate.
Edit: If you want the best place to buy iPod parts, buy them from Elite Obsolete on his website.
It's usually Government websites, and some websites I buy things from.
Even with the protections completely off, it was still borked.
At that point I'd just chalk it up to Starfield being very hard to run so whatever server runs Starfield over XCloud is being heavily taxed.
