Tested a couple of different joysticks in game & on the menu system, up works in the right port but not in the left port... nothing obvious looking at the soldering apart from a lot of flux... the wifi antenna was lodged under the left port though...
Currently imaging the 64GB card, gonna try writing that to a spare 256GB and expanding the partition in linux (PiMiga4.0 x86 distro... I can't remember which linux distro it's based on...)
...that worked I... I think... is there somewhere I can check storage??
Seems faster with the new mSD card in it...

The 64GB had 600MB of unallocated space at the end... I guess that is because the definition of 64GB varies by manufacturer??
