Rom hacking questions

Hey sup Odbarc, long time man. I'll do my best to answer some of these.

1) I'm not entirely sure the command will even show up in battle for another character without altering the code for who gets it. And of course it only shows up normally after the Zozo event so that bit check would probably want to be changed or removed. Yeah Terra would still change into esper Terra for those battle events, which can also be edited, it's pretty tricky but there's great documentation now for those at least.

2) Yes, without changing the character value code at C2/5EE5 Mog will still need to be in the battle to learn a new dance. It's a one byte value change, though, is all.

3) Not too sure, I always forget how the formula for vigor and magical weapons works, hopefully someone could shed light on it.

4) No idea without testing lol.

5) Shock is called 'Megahit' (spell ID 130) and can be edited in the spell editor. Health just calls Cure 2's spell ID. You can change what spell value it uses easily enough at C2/171E - don't be afraid of hex editing!

6) That blacked out  sprite is actually used/reserved for his desperation attack animation, the Fire Dance sprite can be edited easily enough with yy-chr among the spell animation graphics at offset 13EC30, use 3BPP SNES format.

7) No idea without testing.

8) This questions somewhat confuses me, but I'll say the whole Locke steals clothes things is controlled with bits that are set and cleared both in the AI scripts for those monsters/battles, and then cleared in the event code when changing clothes back later when rescuing Celes. It is coded to only be for Locke though, so anyone else should be fine. If you plan to use the merchant and soldier elsewhere and they're used in another formation, you could do a formation check in the AI to not have it do the locke clothes stuff.

9) I don't see how it would as there's only the one inherent Rage spell list. Gau would need to leap more monsters for it to effect the other character's (shared) Rage list.

10) You mean how they join via a battle event? Well, actually they are created and all but added into the party right before the battle in the event code, and then summoned into the party basically via the battle event. But anyways, it depends, some events are coded to be character specific where it calls certain IDs to do movements and etc., so yes sometimes extra event coding will be needed to control a character that is normally not supposed to be there. But other times the game uses a general party member 1-4 command to control characters when it doesn't really matter who's in your party. You can add or remove whoever you'd like really, just more than likely extra event coding will be needed.

11) Changes like what exactly? Animation changes? Trying to make 'custom spell animations' from combining values from other spells is hit or miss and can definitely break the game. If you mean other changes like values to damage or elements, targetting or what have you, that shouldn't be an issue.

12) Yeah all the things you mentioned just call the spell ID, so changing the spell would effect those.

13) Yes, any character that can equip the merit award, will be able to equip heavy flag equipment. Having it be character specific without simply allowing the Merit Award to one person will require making new code.
