Still doesn't solve the problem that the link in the document points to something other than what it tells you it points to...
This document is obsolete.
UPDATE: I have constructed a usable table file. I used this.
It's called yy-chr...it's a tile editor, but by finagling with it, I found out that the address where the game starts looking for the font is 11F000. By looking in yy-chr, I can see:
I simply guessed that the blank space in the upper right was the beginning of the hex data for the font.
This makes the character "Capital A" the hex digit "60."
So I open up Windhex
And pull down the Tools menu. In it, there's a "Table Maker."
As you can see, I've already typed in "60=A," to order Windhex to begin making a table file where "Capital A" means "60" and vice versa. Once you press enter, it'll prompt you for the next hex digit. If you look in yy-chr's window, it'll show you that the Capital Letters and the Lowercase Letters are in sequence...RPGe appears to have done a clean job.
So finish out the Table. You'll have to type it manually, based on what I know. That means 61=B, 62=C, etc. It'll keep prompting you. Unfortunately, if you screw it up, you'll have to start over, as there is no backspace function. Once it's done, click the "Save Table File" option in the File menu. When you close the Table Maker, it'll prompt you to apply the new table to the rom you have open for editing.
There! A basic table file for FF5e.
