Because of request I updated my hangame launcher so it works again. You can get in from my website. If there is demand i may add registration form to launcher, so you don't need to bother with those korean websites to register. But from what i remember only few people here plays hangame, so it may be not worth effort.
see guide by crzy242: Hangame Guide
anyone interested in making english patch or server for it? That would be cool i think.
