I decided to try my own documents and see what I can get.
{I need to explain better how to calculate the pointer table end.
However, thanks to the help from 343 and abridgewater in the RHDN discord
I got a proper dump}

All the info to make a translation for it is here.
[Besides most images seem uncompressed. If not all]

#BLOCK NAME: InitialD (SGB)

Insertion test / proof


Reused the same font and copied the table with utf-8 format to check.
A new font will/should be made.

Atlas code for insertion,
Actual text will require pointer adjustment since it gives overflowed warnings.
But insertion works.

Spoiler:

I was doing a second search to be sure i didn't leave any text and I found, in bank 0x1:

Credits, 2 Character Names' list, some JPN & ENG text menus.

 * I believe one of this Character Names list is for the default name records.

Credits text + Address

The text on this post is undumped, the post will be updated when this text is dumped

This table works in a different way with more bytes, explanation in the spoiler:

Spoiler:

First:
The credit pointer ini is [New] = 0E09CDE00C

Second:
The credit pointer "next" is [New2] = 6506 + "?" ;
Where "?" is a hex value with what seems the position for each subtitle within the menu
The pointer for "next char" is [Char2] = 65C906 + "?"

A couple more of graphic assets

PS: I have to review all graphic assets yet, but mainly English titles like "RECORDS" or "SOUND CHECK" are the only ones eluding my searchs.

We discussed this in the Discord, but I figured I'd summarize here for posterity:
cd e0 0c (at $44a3) disassembles as

Code: [Select]

call $0ce0At $0ce0 is e1 cd 05 0d e5 c9, which is

Code: [Select]

pop hl
call $0d05
push hl
retWhat we have is a code stream with inline literal strings.  The strings are variable-length, so either the length is loaded ahead of time or there's a terminator, and 65 is a good bet for the terminator, especially given the "Credits text" image.

From there, we see (at $44b6) a sequence 06 xx 0e yy cd e0 0c which appears a few times again further down.  This is

Code: [Select]

ld b, $xx
ld c, $yy
call $0ce0and the values used strongly suggest display coordinates rather than a text length.

Sometimes there just aren't manipulable pointers.  Sometimes it's a matter of asm hacking no matter what.

Currently examining the sound code

This is the i/o map:


This is the routine to load the wave pattern:


The game seems to use ASM code to initiate and update the sound channels, not literal strings
More to come
