How to use VZIPFLIP

Yeah no problem. But actions speak more than words. Hit the thanks button.
Eh. I don't really care if you hit thanks but you should in the future for when others are helpful

You edited the files inside the zip and removed the "_" before converting it to hfs?

yes sir i did

Nope, you cant. Nexon fixed it.

Yep .

But there have to be another way of bypass this integrity check.
I've just looked into the heroes.db3 of vindictus and found that some armor/weapon recipes are blocked until EP5 for example. But in the EU Version I found some of these weapons, that shouldn't and aren't craftable, on the market, so some ppl have found a way to change the content of the hfs files without let the game/hackshield knowing it.
The only way might be to modify the MD5 or SH1 Checksum, with a method not known to me.
I've read that it is possible to make 2 files with different content but the same checksum.

Or another method is to modifiy the values of the integrity check...
