Hey im doing vb stuff, this was a quick thing so don't expect some 1337 stuff :P
Basically all you need to edit is the realmlist from 127.0.0.1 to your servers realmlise so like 2disawesome.ath.cx, compile and your done.
You can also change the enUs to enGB for the launcher to work for EU people. Also if your paint skillz are good then you can edit the Play EU button (made 100% by me) to Play US.
Soon i will release the one with both Play US and Play EU but i have not got time atm XD.
