Is this a fan translation, or an official release?

[tag2015]

This is a fan translation, but it's not possible to support it simply adding the detection entry, it requires a patched version of ScummVM.

The translation is available on british-choi's github:
​https://github.com/british-choi/ScummVM-Kor-Trs/tree/master/Broken%20Sword%202%20(Windows%20CD)

These are the commits that add support for this version (note that this is still the old 2.7.1 branch):
