Scene packs (short)

One liblinuwux.so covers modern and legacy Reflex / DenuvOwO layouts (auto-detected). Game markers beside the exe include reflex.dll, reflex64.dll, and DenuvOwO.ini.

Older packs that ship launcher.exe: do not use the launcher on Linux — launch the game .exe directly, same as modern titles. See Launching and Common mistakes.

Host CPU / hypervisor setup is summarized under Prerequisites; full instructions stay on cs.rin.ru.
