Not all needs new translation - maybe You want to use old language files from 1.1.5. It will give You a largely "Simplified" K-Meleon beta. The beta fixes an old bug for big5 support. So it is worth trying.
BTW. I found K-Meleon when it was 0.6 - It still has the same qualities it concentrates on the basic surfing functionality. I do not think it lacks many things
p. s. Simplified translation is not finished - and maybe not yet started.
The development cycle is that while the Versions are beta they are en-US
(the developers speak other languages like: French, German, Spanish - they communicate about what they do and coordinate their work via the en-US version)
When no more work is done that alters strings that must be translated senior users and developers start to translate. Each for his own native language.
AFAIK Hao can write Chinese. He did both CCF and the first official translation.
He is only one man, that is why Chinese translation took long. If more Chinese PPL joined him - simplified translation would come faster.
