Same for me...
Updated to 8.02 and the screen freezes on using retro arch menu.

When i change the controller config on ps1, it starts errors like "memorycard 2 not found" and freezes as well.

Thank you so much for your great work ..but.. updating recalbox is quite often buggy. If i get a proper usable version i think about stop updating.
What about s.th. like a stable and a beta build?
