The noob above me doesn't know either.
Alright, this is the section for hack releases.
You should have posted this in Help.
But, I'll explain here.
First, you need to find a hack.
Spark's MPGH trainer I heard was working after the patch.
You then need to get a bypass, and an injector.
Use Gamelauncher.exe in your Maplestory folder, to bring up the splashscreen.
Inject the bypass, then inject the hack.
Click start game and enjoy.
