Lineage II Old skool launcher (just a backup unrelease) V2

#SingleInstance force
#Include %A_ScriptDir%\HttpQueryInfo.ahk

; Application type and code started :
; 15th October 2014 by Baoulettes aka Joffrey Panisset
; Joffrey.panisset@hotmail.com
; Unauthorized use is forbidden.
; Lib used that isn't writen by Me remain to author and Authorization pending.

;This script use "Runfirst" from :
;
;http://www.activeplus.com/Products/RunFirst
;

; Gamemode Game <-> Dev console will be writen in Option.ini. No need to provide it in "L2OSCheckFileList.ini"
; Options modifier Is there to produce same effect than In game just with few little tweak:
; Change Fullscreen mode, Play on server or Dev console to discover Items, Map.

; I suggest to Manualy update "L2OSConfig.ini"
; And put it in the Launcher file check ini.
; And so it will be better to see both version and that easier to manage.
; Also "L2OSServer.ini" and "L2OSConfig.ini" is the same files only name change.

; In case of Launcher update it can happen, check Global variables to change Version.
; AppAuthor is there only as copyright things and it never seen on the application itself.

; The source of code is provided to show I do but it can be used for learning process.
; A pure copy paste of the code isn't a learning process that is why I comment all part I could to explain how this work and help you later.
; Running this software as it will be useless for you but it can be modified to work on ANY game system or update system without requiring FTP access.
; So in case of hack/flaw in the code all your credencial are safe as it require NONE! :)
; Security first.

; Data Used on compilation change path your path -(can't be variable path !)
; RunFirst is used only if "AltTabFix" is checked!
