SoulSilver hack: Pokémon MindCrystal

djx1100 said:
Sorry i'm new to Hex Editing so excuse me if i don't know exactly how to find it lol
Click to expand...

i used this
[PokeCommunity.com] Pokémon MindCrystal
, then searched 25 63 (yes like that, with spaces and anything) until it found D20 something like here
[PokeCommunity.com] Pokémon MindCrystal
 
Is there anywhere I can find a full list of the changes made to pokemon? Also, is there a location guide for pokemon?
 
Since nowadays everyone and their brother's hack seems to feature the Items chaining, as well as Repels chaining by default, those are going to be implemented in the next revision:

As said in my post, I'm working on a far more detailed documentation.
 
I think I may have found a game-breaking bug: when I enter the room with the electrodes, in Rocket's hideout, and I walk back to fight the Admin and Rocket Grunt with Lance, the game crashes as the battle starts...

1°) Emulator and/or flashcard?
2°) Do you have any cheat code enabled, regardless of the medium you're using?

And, well, this is kind of surprising because I didn't change that map nor the event file associated to it.
But I remember playtesting v2.0 on flashcard and that part of the storyline was fine, this might something to do with an ASM hack then.

Emulator (Drastic). I don't have any cheats enabled (I'm not actually sure how to add them to be honest which is probably an issue for another day).

I also tried taking off the fast foward option and taking my phone off of power saver in case it was because my phone wasn't able to handle the game (in case this is a thing? Is this a thing?) but it didn't help either

EDIT: I transfered my save to my computer and used Desmume. I got a little futher into the battle, but then it froze just as my pokemon and Lance's pokemon are released.

EDIT 2: I tried using an old version of the game and it worked (but its giving me issues when I try to change back to the intitial rom)

Sorry for the late reply.

The source of the problem is narc a/0/0/8, which contains most of the battle HUD including the battle HP templates.
Something went wrong as I modified this narc since restoring the unmodified narc fixes the issue.

I'll edit this post once I find something new.

EDIT: The problem has been fixed, it was because the new HP templates were 8230 bytes uncompressed when they should cap at 4144 bytes, causing the graphics to overflow and subsequently causing the crash.
I'll update the OP with an emergency update ASAP.

Thanks so much! You're the best. I just found an adamant absol so I'm hoping not to have to start a new game.

You won't have to, no worries.
Also since you're already at Mahogany Town, it means that you already defeated 6 Gym Leaders.
Out of curiosity which one did you find the hardest to fight against?

I'm trying to build a team with the new abilities, with the exception of togetic who I've included for the fairy type. So basically, I have beaten every gym leader with just togetic which, given the moves it learns, meant that Morty has given me the most trouble so far. That sableye with willo-wisp (and the ability that allows non-attacking moves to go first) gave me some trouble.

I am playing the updated rom and the bug is still persisting: the game still crashes after the intro to the battle with the admin and the rocket grunt...

Weird…

I patched a ROM from the download link just to make sure that I did upload the right patch, and here are the results:
_DeSmuMe: works
_No$GBA Debugger: works
_NDS* via R4i: works
I'm not able to test for DraStic, however.

*The ability to work on a NDS is by far the most important criterion for me because of its ability to act as a deal-breaker should the hack fail that test.

I moved my save to Desmume, got passed the admin then moved my save back to Drastic. Everything is working again now. Thank you for the help!

Its now telling me that my bag is full when I try to pick up a TM (TM 54)
Click to expand...
If you already have the TM54 in your bag, then it's normal, since it's part of the re-usable TMs feature.
I take it you're in the Dark Cave, right? If that's the case then it's just that I didn't update the item yet.
I do have a list of TMs that appear multiple times, those were relocated accordingly but somehow TM54 escaped my notice.

Yup, this was in the dark cave. Ok, perfect!

Morty has a Prankster Sableye? I'm not looking forward to that. ;-;

Morty's Sableye in detail for the first match:
Code: 
Level: 24
Gender: ♂
Ball: Poké Ball
Item: Focus Sash
Ability: Prankster
Nature: Careful
Move 1: Will-O-Wisp
Move 2: Sucker Punch
Move 3: Metal Burst
Move 4: Recover
There are ways to completely shut him down or at the very least put him at a disadvantage:
_a Pokémon with the Ability Magic Bounce will severely cripple him as he burns himself with Will-O-Wisp (Espeon evolved from a Adaptability Eevee if you grind like crazy, most likely Natu* or Xatu at this stage of the story)
_a Fire-type Pokémon will do well,
_so does a Pokémon with the Ability Water Veil or Magic Guard**,
_a Pokémon with the Ability Flash Fire works too (Cyndaquil's line, for example)

*some Headbutt Trees in the Ruins of Alph hide Natu; since you can get Headbutt as soon as you catch a Ponyta on Route 46 you can try your luck and wait for a Magic Bounce Natu to appear.
While Natu is part Psychic, it fares really well against Sableye (as long as you can play around Sucker Punch), even more so as a Xatu since it gets Air Slash as soon as it evolves plus you can buy the TM04 Calm Mind at Celadon Game Corner to teach Natu/Xatu the move.

**The Odd Egg may hatch into a Magic Guard Cleffa (who has a 49.9904% at being shiny), you can soft-reset as many times as you want since the species and the PID is determined the moment you take the Odd Egg.
