A bypass will certainly work without emulating the AntiCpXServer authentication scheme. You are right in the fact that this a AntiCpXServer emulator, albeit not one written for Vindictus's HS version. It is not clear if they are using different versions of HS or if one of the flag type responses is hardcoded, i.e. I don't care to check. If both the aforementioned claims are false, however, then this emulator should work.
