# services/selkies.nix — Guild Wars in a browser via Selkies
|
||
|
|
#
|
||
|
|
# Replaces the Neko attempt (services/neko.nix, now unimported): Neko's
|
||
|
|
# absolute-pointer input model can't handle Guild Wars' exclusive mouse grab.
|
||
|
|
# Selkies captures the mouse client-side with the browser Pointer Lock API and
|
||
|
|
# sends *relative* movement, so the grab is a non-issue — and it uses the GPU
|
||
|
|
# (NVENC + EGL) instead of software rendering.
|
||
|
|
#
|
||
|
|
# Reach it at selkies.nordhammer.it (Authelia-gated). The Wine prefix with
|
||
|
|
# Guild Wars already installed is reused from the old Neko home, seeded into
|
||
|
|
# /var/lib/selkies/home/.wine (see the deploy note in the repo).
