Goal of this Research:

Create a new subroutine in the game to allow MP Drain digits to offer a new color, versus HP Drain.

• Identify which routines are used during battle for MP Drain
• Write Branching logic to Jump to the new subroutine in all of the existing routines
• Write new subroutine to
  • choose a blue versus green color for digits when MP is gained
  • choose a red versus white color for digits when MP s lost

Assumptions:

• Existing routines to assign colors to the digits can be leveraged for this new subroutines
• The new colors assigned will automatically clear whenever another digit sequence appears
  • (No need to clear them)

Notes & Findings

There are 6 ways for player characters to drain MP in the game:

• !Dance Ability, with the Mystery Waltz
• !DragonSword Ability
• the Psych spell
• the Psych Sword attack
• the 1st Lilith Kiss Mix (Maiden's Kiss + Ether)
• the 2nd Lilith Kiss Mix (Maiden's Kiss + Elixir)

The two Mix recipes are almost certainly different in a lookup table, but it’s uncertain if they point to the same effect routine in the rom.

Any monster abilities that also do this may represent a 7th or worst case scenario, nth possible other routines.

<aside> 🤔

Maybe it’s possible to hook into a central routine that runs downstream from all of these! After all, there are main ways to gain HP and they all resolve to green digits!
