Every once in a blue moon, I get the question about whether or not a Devilian private server OR the server files exist. My response isn’t much different from what I wrote back in 2018 (except we now know that Krafton took no interest in doing anything with the franchise, and have since ended development of TERA PC, which Devilian ended up borrowing heavily from after Bluehole acquired Ginno Games).
The emulator that was used to create some walkthrough videos of a Chinese mobile knockoff called Dark Faith (it must have gotten a cease and desist from Bluehole since the assets/look of the game were completely changed one day), has never seen the light of day either. The occasional lead that pops up is normally just the client files. And yes, I have tried searching pan.baidu.com for 恶魔契约 (the CN name for Devilian). It’s been over 4 years now, so the likelihood of there being anything is slim to none.
