If you can't answer the question, it would be better not to post.
How hard would it be just to translate the menus in this game?
It would take a lot of skill, because it uses a custom compression. If you can build yourself a decompressor, then you'll be able to translate the menus.
Could it be done in less than a week?
That depends on the knowledge you have.
If you can program, understand what hex/binaries are, and can figure out the file format of different files, you'll probably get a menu trans done in less than a week.
Could it be done on a iMac?
Well if it supports different compilers of different programming languages, and has hex editors that can run on the iMac, then it is possible.
