Bypass patching? Old bypasses useless

[Marty McFly]

Hello folks,

I recently tried to mod my metin2 client (short info - I'm on the official GameForge EU servers) but of course, the altered files are detected by the patcher and overwritten. Short researched showed me that executing the bin files instead of the exe files should work, but it doesn't, it gives me the ERROR_CODE 20001. Any guide is outdated, so is there anything I can do to use modified files?

Thanks in advance!
