like i said its a assumption. i have not seen the whole container of files.
And 500MB+ of data is really alot. so i cant really guage with the whole thing, being inexperience with hacking and translating and stuff.
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...
