Sorry I haven't got back to you in a few days. Like you mentioned, when I am working on games, I have been extremely busy with Zero no Kiseki. Last I looked at it, I got stuck trying to figure out the tpl files (image files from my understanding of looking on the net). I haven't found a program that recognizes them and will open them. I haven't given up yet on finding the stuff you asked about. Might take a look after I get annoyed with Zero before bed.
Edited Part
Found some goodies. It's Shift-Jis encoding (CP-932 is another term for it). Begin your search in the eboot at 0x2E9D20 and as far as I can tell 0x306370 is the end of it. Don't quote me on that. I tried to use various dumping tools to make you a spreadsheet but they came out a horrible mess. I tried Flamethrower's Eboot dumper and another program called TED (you can find it at romhacking.net in the tools section) if you wanna give it a go. It wouldn't be so bad if it didn't have a ton of trash in between the bits of dialog.
A good portion of the games files are NOT compressed/encrypted. You should be able to do something with the game atleast. I will suggest you find somebody who can add "single width latin characters" to the game. It does not support them (it doesn't crash but they won't show up if you try to use them). It does support full width latin though (the two byte A-Z and a-z style).
I hope this helps you out in some way. Let me know if you have anymore questions. I'm off to bed. It's 2:22 in the morning and I have to rip a bathtub out tomorrow.
