[Release] Flyff.a Bypass

Page 6 of 7 « First 45 6 7

I have complied the bypass. I have tried basically all the MD5 hash codes..
Nothing will work. Client keeps crashing before login screen.

Here's my steps:
1. I open the client loader.
2. I open the bypass.
3. I put in the MD5 hash(I have tried the Flyff.a, the data.res, the changed data.res)
4. I start the client and it crashes..

If someone would kind enough to explain it in English? I'm trying to learn German but it's hard without living there.

Can you teach me step by step? I don't know how to use the codes.

Instructions:
1. Fully patch fame/whatever server you want to use this on(if it uses flyff.a it should work)
2. Copy their Flyff.a to the folder where this bypass is.
3. Remove the contents of Flyff.a and edit the .res files to your liking
4. Run the game and use the bypass at the login screen.

now log in and you're done.

All the code except for FindPattern, DataCompare and md5.h is mine.

It would be nice if you explain me how do you get the following pattern:

Hi. It's too hard to understand! I mean, I don't speak your language so it would be better if you make a/an english version of this tutorial, though i can barely understand it. I really don't know where to put those "PHP code".. maybe you could be more brief. do we need to use C++ on this thing? I'm hoping for your reply.. thanks in advance.
