Shock Ability

I'm not a coder by any means but it's less complicated if you know where to look.

If you go [here] it is disassembly of C2 (Assassin / Terri Senshi) and search for Shock you get the following:

Code:

Shock

C2/171A: A9 82        LDA #$82       ("Megahit" spell, which is what has Shock's data)
C2/171C: 80 02        BRA $1720      (go set that as spell/animation)

So if you use a coding tool (I use WinHex32) you can search for those pointers and make edits accordingly. I think this area might be relevant:

Code:

C2/57AA: BD 00 00     LDA $0000,X    (get spell # from menu)
C2/57AD: 30 0A        BMI $57B9      (branch if undefined)
C2/57AF: EB           XBA
C2/57B0: A5 EF        LDA $EF
C2/57B2: 10 07        BPL $57BB      (branch if character not an Imp)
C2/57B4: EB           XBA
C2/57B5: C9 23        CMP #$23    
C2/57B7: F0 02        BEQ $57BB      (branch if spell is Imp)
C2/57B9: 38           SEC            (spell will be unavailable)
C2/57BA: 60           RTS


(Set Carry if caster lacks MP to cast spell.
Clear it if they have sufficient MP.)

C2/57BB: BD 03 00     LDA $0003,X    (get spell's MP cost from menu data)
C2/57BE: CD 4C 3A     CMP $3A4C      (compare to Caster MP + 1, capped at 255)
C2/57C1: 60           RTS

But again, I'm a novice when it comes to coding so take this with a grain of salt.

I hate to be a spoilsport, but as madsiur communicated, it isn't that easy.

The battle menu is designed to only allow Magic (including the Equipped Esper) and Lores to deduct MP. "But isn't Shock a spell?" It is...but it's not a spell in the same way as Flare or even Aqua Rake is, each with spots allocated in the menu and an MP cost defined.  The code in the second part is useless because it only refers to the Magic/Lore menus, and Shock is not normally cast out of those.

There are then two ways of going about this.

1. Adding a 'Megahit" clone to the learnable spell list by creating a new spell than can be cast (advanced).
2. Rewriting the "Shock" command so that it costs MP (and what would you like? A mini-window like with Lore/Magic with Shock as the only option? For the command to be used and succeed and deduct the MP without fanfare if successful, but fail otherwise?...this is also advanced)

It's possible and the outline on how to proceed is straightforward...but this is not easy by any stretch of the imagination.
