if they had LAN multiplayer it worked 100% of time. There was this one case with Red Alert where it would disconnect random times, but I never played official vesion so who knows maybe it would be same.
Steam games also work but you need to wait until they get hacked.
Take a look at online-fix.me website. Their games always worked cor me and my friends, just register on it, otherwise they dont show download links
Don’t use Raspberry pi.
A cheap old laptop will work a lot better.
I think Raspberry pi is only good if you need gpio, otherwise save money and use an old laptop.
well, it’s available on my Jellyfin server
