Hey, was wondering, on 'setlang.bml', what is the deal with '简体中文 (中国 （単純な） or （単純）)'<--this? Are you trying to convey the simplfied Chinese idea? If so, maybe you can just put 中国語(中国）中国語（台湾）or maybe simply replace the country name by 簡体 and 繁体 respectively, since putting down Taiwan for traditional Chinese might not be entirely appropiate.
... Actually, I guess I'll think about it some more. Just wondering if that is the meaning you want to convey.
