It’s a bit unfortunate, that the only way to access GameVault is via a client from the Microsoft Store.
Does it at least work in WINE?
Edit:
00d4:err:virtual:virtual_setup_exception stack overflow 2000 bytes addr 0x170030d60 stack 0x20830 (0x20000-0x21000-0x1a0000)
It does not seem to run under WINE.
You must log in or # to comment.
The client is also available on GitHub, to be clear.
I believe they are working on a web interface to cover this, which is listed on the roadmap: https://github.com/orgs/Phalcode/projects/4?pane=issue&itemId=35193982
Though as you can see it’s not feature complete.
