These are mainly for Phoenix, but they could benefit anyone else who wants to work with this version:
Pointers, these are headered, parts of larger subroutines but I found them the "traditional" way as it's faster:
0x0A4D9 Item menu "Nothing here." pointer.
0x0A548 Item menu "Cannot use here." pointer.
0x0A610 Item menu "Whom?" pointer.
0x0AAC3 Status menu "For level up" pointer.
0x0B1B6 Magic menu "Ninja" pointer.
0x0C615 Shop menu "Which one?" pointer.
0x0C9BB Shop menu sell "Qty? 1" pointer.
0xF801E Menu Japanese DTE Table - Starts at $0F.
Subroutines:
$01/83D5 Character Name Printing Routine
$01/8B41 Character Class Loading Routine
$01/B29A Magic Menu Spell Name Multiplier and Loading Routine
$01/B326 Magic Menu Spell Name Printing Routine
$01/BFF0 Character Class Printing Routine
$02/9DD8 Battle Item Menu Item Name Multiplier Routine
$02/9E29 Battle Item Menu Item Name Loading and Printing Routine
$02/9FBE Battle Item Menu Equipped Item Name Multiplier Routine
$02/9FFE Battle Item Menu Equipped Item Name Loading and Printing Routine
Hope these are useful. Note that I didn't go out of my way to find anything I didn't need for my hack, and I forgot to note a few subroutine offsets (Mostly related to item names in the menu and field, one of the first hacks I did). I'll amend this with other findings or anything I forgot to post later.
