Current issues

  • Game fails to install

  • Game crashes randomly during gameplay
  • Game does not work with keymapping
  • Game experiences graphical issues or broken UI
  • Game fails to connect to servers or complete download

I tried the game both on the latest Release (1.1.1) as well as the latest Nightly (53). I also uninstalled the Game and re-installed it for each Version.

Edit: This is the screen in question the game gets stuck on

I know how to fix stucking at Verifying downloaded file. But it will not work either because of NGSM(Nexon's anti cheat solution). Game will show alert same as MDNF(https://github.com/PlayCover/PlayCover/issues/57)

Any idea on what it might potentially check? I am working on an option to not inject PlayTools (so that games detecting dylibs won't get tripped), but if it is something related to the game executables, it would be a nightmare to do.

I should also mention that the game seemingly has no Jailbreak Detection, as it works as it should on my Jailbroken [checkra1n] iPhone 6s and 7 (both which are primarily used to dump and decrypt IPAs).

That said, if there is anything I can/should test or can do, I'd be more than willing to.

The issue being that it might not just be anti-cheat, but also anti-tampering

Can you try reinstalling the dumped IPA into the device and see if it still work?

Well, not Sideloadly (which signs the file again), rather, maybe try installing a patch like AppSync Unified from Cydia and install the unencrypted IPA that way. If it still trips, we know for sure that is integrity check since apps are permitted to read their executable contents

The dumped IPA cannot open on my iPhone 7 after I re-installed it, but that may be an issue with my iPhone. I will try with my 6s as well.

Another thing. I downloaded the Japanese Version on my iPhone 7 to decrypt and play around with. The JP Version however detects my iPhone being jailbroken and closes the game after a short time with "Illegal Program detected" and closes. That did not stop me from dumping it however. A-Bypass and KernBypass were also unable to fool the Game.

Now here is the weird thing: the JP Version installs without issue with PlayCover, opens, downloads assets, and can be played. It needs the Jailbreak Bypass Option set, otherwise the Game will throw an "Illegal Program detected" exception, and then just works.

So, the JP and Global Version must differ in some tangible way when it comes to their JB detection.

Blue Archive JP has been fixed in version 1.0.6 by Lucus but I don't think Blue Archive EN ever worked.

Yes JP version is whole different game. It uses XignCode for anti-cheat solution not NGSM.
