This provides 2 gigs of ram to minecraft, and sets default java processing language to english.
change 2048 to anything you like, but I recommend it to be a factor of 1024 kilobytes (= 1 gigabytes).
Let me tell you how I came up with this:
Packs do not run well with less then 2 gig ram. Since the launcher is bugged, it doesn't let you allocate 2 gigs of ram. so you do it manually.
One of the most important mod, codechicken core does not work well if your OS languages letters are latin based but different. For example, in my case, in Turkish I and i are different letters and they both have their own capital forms. for example, we have a capital i and a small letter I. When a code asks the OS to turn a text into full caps or small letters, windows obeys the rules of the language your computer is using. SO, if a mod sends the command "initiate" to codechicken core, command gets turned into "INITIATE" in english language, and works well. but in another crazy language like Turkish, command is parsed as "İNİTİATE" which makes the game crash to doom(or do nothing).
