So you can't play version 0.49, because "game is always online" or you can?Not a Steam/Denuvo emulator, the game is always online and everything is tied to Helius servers. Even if you cracked Denuvo the game would still be a brick because it couldn't access the servers.
If you can, that's because of Golberg server emulation crack, and you wrote nonsense.
And Golberg has nothing in common with Conquistador (I believe that's name of guy) crack. Maybe he cracked some version before 0.49, but Kirito uses not his, but Golberg's server emulation.
If somebody cracks Denuvo, there is no problem to continue use this server emulation.
