You can use my script. Can be fed to the client no problem and used to run faf games.

This will be integrated into the client in the future (tm)

In addition to FPU shenanigans, lightly quoting Marcan, the cores in the M1 speculate execution extremely hard, and that is making pre-existing unknown bugs surface. It's possible FA itself is broken in a way that never shows up in Intel/AMD cpus, and if that were the case it's probably pretty much unfixable.

It would also mean that the game would likely stop working at some future point when x86 cpus get more complex and trigger the bug. (you can talk about retro compatibility being x86's only reason to exist though and argue that last point may never happen)

In the ideal scenario, your game packets aren't relayed through our servers, but you do need an external public facing server in order to establish a connection between two players behind your typical home router.

The issue comes with people with dysfunctional ISPs and/or ISP router which don't allow for this (UDP Hole punching) to happen, then we need to actually proxy the entire game from every user to every user in a centralized manner. This is surprisingly common nowadays, sadly.

Having more servers to bounce the game helps, such as the australian TURN server. We are working to get more alternative turn servers running. Yesterday we were testing one for a while and got good info. We will post an update soon.

The countermeasures to stop recent DDoS attacks on the server don't allow for other turn servers other than the one in germany to function. We are working on a solution and will post soon.
