TULUKA is a powerful AntiRootkit Detects hidden processes, drivers and devices so if your using an OS which is 32bit you can see the hidden process of Grand Chase "Main.exe"
btw i try this but it seems somethings missing on his TuT, first of all if you put the engine in Folder Lock and you locked it you can't open the Cheatengine.exe unless you unlock it to run. Second is if you use Tuluka in 64bit os it will not open because it was been blocked and automatically close the program. I already tested it in GCPH seems doesn't work at all. UNABLE OPEN THE PROCESS! =)
