Open notepad -> Copy the quote > Paste quote in notepad > Save file as "registry.reg" > Double click on "registry.reg" that you created
You now have tons of SC servers. This should give you access to the Korean servers Fish, brain, mapzine, etc as well. Logging onto one of the default gateways may clear your server list, if this happens, you can just double click on your "registry.reg" file and it will fix it every time.
I hope this helps.
