Translating in-game contents - 2 to 3 months
Fixing up weird things that happen after translating - 9-12 months
making the whole game look presentable - unending.
this is my assumption of the time it takes but i could be wrong.
they dun have to proper tools to start with and things like this make it harder and had to make their own. so unless you can contribute, dun whine. it makes everyone angry for no reason. I, for one, wish that i have some ASM knowledge, so at least i can contribute to something i want to see done.
