Need some help to finalize AmigaOS4 port of AssaultCube

[tempest]

You pass --home to AC as a command line argument when you start it. Like

[SELECT ALL] Code:

bin_unix/native_client --home=/some/path

(I have no idea if your binary is in bin_unix since you're not using a UNIX system...)
Now, that /some/path has to be something you have write permissions for. I have no idea where configuration files are typically stored on Amiga, on Linux it would be ~/.assaultcube_v1.1
