yes. yes you may think "this has been done before" blah blah blah,
ive re-created it. ive made it so when you open it, it goes directly into your minecraft saves
so that way you dont have to keep looking for the pesky directory...

i made it so it works with tekkit!

HOW TO USE: SIMPLE!
step 1: download the gamemode changer
step 2: open which world you wish to change to creative, survival or hardcore
step 3: double click on the " level.dat " file
step 4: choose gamemode
step 5: Enjoy!

NOTE: for this to work, you must get out of the game (not minecraft itself)

so... enjoy and give me a diamond :) :D
