Changing the the sprites chocobo-riding uses
« on: September 11, 2010, 07:10:34 PM »
I noticed the characters each have a set of unused sprites (right next to their tent sprite) that are either blank or filled with japanese letters for each character.  The weird thing is, these sprites are also blank for Leo and Banon also (attached is an example of what I'm talking about - a screencap of FF3UsSpriteEd with the unused sprites in question for Leo).  Would it be possible to change which sprites are used for the chocobo-riding to utilize the sprites in this location instead?  Then you could paste each character's chocobo riding sprites into the unused space, and add Leo and Banon chocobo-riding sprites to this area as well.

Crap, it looks like Terra (and only Terra) uses that slot.  However, it's probably used only in specific events.  Those could be remapped to use the old chocobo-riding space.

I already have custom sprites for Leo and Banon (from the other thread) - I'm asking about modifying the locations the sprites are loaded from for chocobo-riding so that there's enough room *for* the Banon and Leo sprites

The sprite Terra uses in that space is never used in the game. :angry: See? :happy:

In order to change which number in the sheet chocobo's use, you'd have to find what sets it, which is likely in C0. It's town/dungeon based, so it has to be there. As for the overworld stuff, you probably won't have to change that, but if you do, that's gonna be in EE. No, I don't know where this code is, cause it's not something I've ever bothered to look for. :cycle:

Well I was able to locate and modify the character's pose when he *dismounts* from the chocobo... it's gotta be near there.  The vehicle code (chocobos, airships) is in bank EE.

Re: Changing the the sprites chocobo-riding uses
« Reply #7 on: September 16, 2010, 06:58:52 PM »
Figaro guards have riding poses, but are otherwise typical NPCs lacking most poses. Wouldn't this method mess up either them or one of the NPCs between their normal poses and their riding poses? (Unless you've changed that about them I suppose.)
And unless there's a bugfix for it out or you're not planning on taking him out into the overworld, you'd still get the sprite glitchup with Banon, right?


Here's why the glitchup happens:
Code: (Novalia's Disassembly: Overworld chocobo rider sprite) [Select]
EE/8943: ADFB11  LDA $11FB      (Sprite number for map character)
EE/8946: 8D0242  STA $4202      (Save as multiplicand A)
EE/8949: A9A0    LDA #$A0
EE/894B: 8D0342  STA $4203      (Set multiplier B to 160)
EE/894E: EA      NOP
EE/894F: EA      NOP
EE/8950: EA      NOP
EE/8951: AE1642  LDX $4216      (Load the product)
EE/8954: 866A    STX $6A
EE/8956: A916    LDA #$16
EE/8958: 8D0342  STA $4203      (Set multiplier B to 22)
EE/895B: EA      NOP
EE/895C: EA      NOP
EE/895D: EA      NOP
EE/895E: AD1642  LDA $4216      (Load low byte of product)
EE/8961: 18      CLC            (Clear Carry for addition)
EE/8962: 656B    ADC $6B
EE/8964: 856B    STA $6B
EE/8966: AD1742  LDA $4217      (Load high byte of product)
EE/8969: 656C    ADC $6C
EE/896B: 856C    STA $6C
EE/896D: 18      CLC            (Clear Carry for addition)
EE/896E: A56A    LDA $6A
EE/8970: 6980    ADC #$80       (Add 128)
EE/8972: 856A    STA $6A        (Save changes)
EE/8974: A56B    LDA $6B
EE/8976: 6901    ADC #$01
EE/8978: 856B    STA $6B        (Save changes)
EE/897A: A56C    LDA $6C
EE/897C: 69D5    ADC #$D5
EE/897E: 856C    STA $6C        (Save changes)Basically, the routine assumes that each spriteset's data takes up 0x16A0 bytes. But since that isn't true for Leo and the spritesets afterward, the offset it uses is wrong.

Admittedly, it isn't hard to change the routine to fix the problem.
