First Possibility: Tom said it, use the Integry Bypass and the "normal" Flyff
Secnond Possibility: neuz.exe...You look for "neuz.exe" in your Flyff folder. You make a link (.lnk) to the Desktop, now you click on "Option,properties" (- I don't know how it is in English^^)
There are 2 parameters:
"C:\Program Files\Gpotato\Flyff\Neuz.exe"
and
"C:\Program Files\Gpotato\Flyff"
The red marked Parameter you have to change in "C:\Program Files\Gpotato\Flyff\Neuz.exe -sunkist"
now you can start Flyff "normal" an with this link of the neuz.exe
Nix Neuz hat mir einer ingame gesagt und es funzt auf die art auch des flyff sympol auf em desktop starten warten bis das spiel gestartet hat und danneinfach nochmal starten
Nothing to do with Neuz you just have to do a double click on your desktop icon and start the game when the game startet (log on screen) just double click the desktop icon again^^
Works perfectly on my Pc and a freind of mine is dual clienting like this too
