FINALLY! SOMEONE ELSE APPRECIATES SECTION [9.0]! We have much to talk about, my friend.
And to answer/comment (bleh 'comment you' sounds weird) you in no specific order:
1. MNG's
bypass is caught, but if you can find other means to get around Hackshield, all the functions should work.
2. You probably won't get banned for using any mods here, nor MNG, but there's a possibility of getting banned if you show it to others/post on Nexon forums with mods showing in an image or other form of multimedia.
3. Don't bother changing Oasis.dll, you'd rather keep it as is. It's just wasting your time changing it.
4. Of course you're welcome to post here asking about this kind of stuff (Unless Playtime/another mod comes and says "Nope". If Kisa says "Nope", it's probably fine
)
