Ok, an update for 8 months later. Registered with the link Ultear posted, got banned. Now I downloaded Line on my phone, made an account on it and registered on cafe with line. Works great now. Also, after u enter on cafe.naver.com/hmrpg when trying to see a post u need to complete a form.
This is the form. In the first one just answer with something. I typed yes. And in the second one you can't have the same username or sth. Just dodge it by typing a number after it or changing your name in another way. The last one is a captcha code. Then tick the box and press the button and you're done. You'll be able to see the highlighted posts(the red ones). To see more posts you need to post replays in their category. For the replay: Topic name: *Name* / *Char name* *level of load*-*level of last save* Topic content: Edit under 2. 저장된 메모장 복사 붙여넣기 With the last save of that game; Then upload your replay. This is how it should look like in the end:
