[REQUEST] Pokémon FireRed - Rematch Gym Leaders

[Ixkli21]

Is it possible to make a Gameshark/AR/Codebreaker code that allows a rematch of Gym Leaders? If you need a .SAV for the point of Brock before battle, I'll give you that.

Here is a .SAV of before the Brock Battle. https://www.mediafire.com/?mrdytod7tbgjd7r

Alright, it's time I help out a little bit... this is a rematch script I've made for Brock with some quick studying in scripting... (I did have some help, of course; a la chrunch at Pokecommunity.)...

This tells the game, "Hey, the player's got Brock's Boulder Badge. Now, we can let the player rematch him as many times as desired as long as the Boulder Badge flag is cleared." Now, can a code be made out of this somehow, or am I still missing the point entirely/it's not that simple?

[Helder]

If you use the no$gba emulator or even MESS (if you can configure it properly) you can put a breakpoint on that flag address and see what changes it and make alterations to the assembly. Is there a RAM address for the Flag?

[Ixkli21]

The RAM address for what flag, exactly? Some specification, please? You mean the flag that checks for the clearance of Badges? That's 0x2B. For the BoulderBadge, that's 0x820.

"checkflag FR_BADGE_1" = 2B (0x820)
"settrainerflag" = 62
"trainerbattle" = 5C

I am grateful that you have went through all of this trouble, MasterGrand and everyone else, but there's something you forgot to mention about your code... you can actually battle any trainer... but first, the code must be disabled before you talk to the trainer you want to fight, enabled after the message box, and then disabled while talking to that person and after fighting them so you won't be stuck in a loop.

Oh, and after the fight, the background music for the map usually muted.

That is right, I forgot it

[Ixkli21]

That is right, I forgot it

One more thing, your code only remembers the last trainer you fought, esp. event trainers like say Blue at Pokemon Tower or Gym Leaders. It doesn't take you to an exact trainer after talking to someone. Say: 0x19E is Brock's flag, but this code only remembers the last battle you have/looks for any trainer data in the person you talked to. Just thought I'd fill in some blanks for the curious.

That, and I think there's one more missing piece that does exactly that: take you to that exact trainer flag.

A more accurate title for the code, IMO, is "Rematch Any Trainer".

[Ixkli21]

I'm looking for the address that stores the hex of the last trainer that was fought, which is what this code relies on. Let's say you battled Gentleman Lamar on the S.S. Anne, right? His Trainer ID is 0x1E3. Now, what I'm looking for is an address that stores this Trainer ID... where would I find it?

[Ixkli21]

That is right, I forgot it

I'm wrong, it was something in the WRAM... and this is the memory address for the trainer: 020386AE:XXXX. This uses the trainer index of the trainer you last fought. By default, this is 0000.

Never mind, I found out how to do it.
