Text boxes in battle - Magic/Trap/Ritual
Usually you'll be outside of Bank 06, since you'll be mostly calling these for card effects and lingering effects such as Swords of Revealing Light.
So do a rst 08 to Bank 06, grabbing the pointer at 6:400B, with the textbox ID in accumulator as the parameter.
3E 13 ld a,13 ;0x13 is Stop Defense textbox CF rst 08 => 0B 06 ;Display text box
The parameter you send in accumulator is also used to retrieve up to 3 card_ids stored in three arrays at 6:41F3, used by display_textbox_func at 6:41B4.
You can display these card_id names in your textboxes using the special character codes (in DM3, these are 0xB5 to 0xB8, but it might be different in DM4, I will check).
