Yes, it's true: Lenophis took it upon himself to fix one of the more annoying aspects of the game, from a text hacking perspective. As anyone who has tried to utilize DTE for text that appears in battle knows, you would normally get a single garbage character, instead of the two expected characters. This is because the battles were still using the Japanese game's DTE table, which was used to print (han)dakuten over top of another character. This patch corrects that, and DTE can now be used anywhere. This should allow for more in-depth text hacks, without needing to repoint strings to any tiny bit of free space in the bank.

You can get the hack here (http://www.romhacking.net/hacks/603/), at Romhacking.net, for the time being. I'm sure Leno will add it to the site once he's back. (More on that here (http://slickproductions.org/forum/index.php?topic=1240.0).)
