Ledah Ending Added? (Spoilers) Options

[Leyviur]

I got a text dump of the PSP game. Apparently there's a new ending:

Ein: ...
Rose: What's wrong, Ein? Why did you come here?
Ein: I don't know... I just felt like I needed to.
Rose: This is where it all began, isn't it?
Ein: Yeah... where Ledah and I first set foot in Riviera...
Rose: Ein...
Ein: It's alright. I just still can't believe he's gone.
Rose: I'm sure he'd be happy that you still remember him.
Ein: Yeah, I guess so. Let's go back.
Rose: Okay.
Rose: Wait, who's there?!
Ein: Huh?
Rose: What?! It... can't be!
Ein: ... Ledah?

I would guess there's no CG associated with this since the CG number is constant with the Japanese CG number + deleted bath scenes, and also it might be unlocked with the same steps as the Rose ending, just with a different girl. Thoughts?

No, you do this.

Say the word is "death".

Calculate the differences between the letters:
d
e = d+1
a = e-4
t = a+19
h = t-12

Then you write your OWN program to read the ROM. It reads the bytes one at a time. It first takes a byte, then checks if the byte after it is exactly one more than the first byte. If it is, then it checks that the byte after that is 4 less than the second. Then 19 more than the third, then 12 less than the fourth. If it gets this far, it will then spit out the address of the first byte. If not, it starts the process over with the second byte.

I get it. Thanks.
