Dammit, I'm doing something simalar to this with Mother 3.
What I'm doing is Using a program called Skype, having a conference call, emailing everyone the script, using Audacity to record it, then finally putting it over the Gameplay video, recorded earlier.
Annnd I thought I was being semi-original. Oh well.
Anyways, maybe that will help, or not...
I reallllly need to read closer. I can't help, as I don't know Japanese!! If I was doing CT, I would probably have Crono ask his mom why the hell she's speaking in Japanese.
AND I NEED TO READ CLOSER ONCE MORE
If you do the English one, I'll help. Just give me someone to be.
EDIT ONCE MORE:
Damn, why did I even post before reading carefully?
I'll send you the Innkeeper lines after I get home.
If my voice is sufficient, I'd like to be Frog.
