-added another neek check, may helps with older neek revisions -replaced the "Disabled" hooktype by "AUTO", meaning it will automatically set the hooktype VBI for you if you want to use cheats but forgot to select a hooktype -added debugger pause back, it will be automatically enabled if you just use debugger but no cheats (thx skidau for the small fix needed)
