IKA9nt.Decryptor

Simple patch to inject a interctive console, mainly for AIdealRays, might support other IKA9nt.Encrypter games (theoretically, not tested however).

• Let the game decrypt bundles itself!
• Change screen resolution, refresh rate and V-Sync settings.

Use the Mod

• Dodnload MelonLoader v0.6+(IL2CPP) from releases and install it to your game directory by following its instructions.
• Copy IKA9ntDecryptor.dll to the MelonLoader's Mods folder.
• Run the game, the console shold appear.
• run "help", and you know how it works.

Note

Though we've decide to let it go, we still generate the AREK.txt during the decrypt process anyway. Check AREK.txt Regex for more info.

Build

• Follow the instructions on Melonloader Wiki and setup your build environment.
• Add the source files in MelonMod folder to your project.
• Build the solution.
