Repacking .pak files

[orpheusT]

I'm currently scouting if Leaf's "Kimi ga Yobu: Megiddo no Oka de" will be easy to translate from a technical perspective, and the prospects look favorable. I used asmodean's exlac (http://asmodean.reverse.net/pages/tools_index.html) to unpack the game's .pak files and the event script was easy to find. Thinking in advance, however, I'm wondering however if someone could take a look and see if there's a way to repack the game files asmodean's exlac unpacks. I uploaded a sample of the game's .pak files here (http://www.megaupload.com/?d=41D5FQH4) and asmodean's tool can be obtained from the website I listed above. If anyone could take a quick look at this for me, I would really appreciate it. Thanks in advance!
