Hi,

i'm modifying USUM games with pk3s. Is there a method to make trainers smarter?

I've flagged all 3 AI bits (basic, strong,expert) but the ai doesn't make right choice sometime.

Is there a method to force AI to use stats move first (sword dance, nasty plot or other) before attack?

I noted that if the AI can 2 hit ko my pokemon never use stats move first; otherwise if would necessary 3 o plus turn to ko, use stats move first.

Also Poke change flag seems not work for some trainer. Works only for the trainer that have this flagged defalut programmed (important npc)

Someone can help me?

Thanks a lot

HI, do you know why my 2023 pk3ds tool would have issues extracting a 2021 omegaruby.3ds file? here is my error log.

hello i have a question, is there a way with pk3ds (or another tool)  to allow more than 32 pokemon box? it's fishing boring to have incomplete living dex cause of this limit

thanks for any people that can help me

[Kawhi]

Whenever I randomize moves my pokemon always start off with moves like absord or leech life, is there any way to fix this or is it my rom or something?

Check the randomization settings. Low-powered moves are intended to be given instead of higher-powered moves, for a more balanced early level experience.

[Zambouni]

I can't get the randomized Poke mart items to the markets, I've made the whole process many times from the beginning but nothing seems to work..
Any help or tips with that?

[ShadowRock9]

Hi, hoping to get some help. I am attempting to remove legendary pokemon restrictions in ORAS battle maison (https://projectpokemon.org/home/forums/topic/39258-solved-some-progress-i-mightve-made-in-removing-battle-maisonbattle-tree-restrictions-banlist/)

 

Currently I have already used pk3ds to extract an Omega Ruby .3ds file, and subsequently have already edited the rom file a/1/7/0 with a hex editor as per above instructions. 

Not sure if it matters, but opening the folder that contains the exefs and romfs folder in pk3ds yields the error "failed to load game data from romfs. please double check your ROM dump is correct. Access to path 'backup' is denied."
I am now unable to rebuild the .3ds file after I open it in pk3ds. the option to do so is blanked out; only rebuilding it as a CRO is available. This is where I am stuck at at the moment. 

 

Any help is very much appreciated. thank you.

[Xeno-Maze]

Hello, I would like to know if it is possible to give an attack the map effect of an HM ? Like for exemple, giving to "Oblivion Wing" attack the effect to fly to other cities ?

To whom may answering, thank you.

Hi, I'm trying to change the Pokemon appearing in each zone but when I want to save this message appears

 

[Pololeroux]

Hi everyone,

I wanted to randomize Omega Ruby but even if I change the starters in pk3ds, my starters in game will be torchic, Treecko, and Mudkip. The only thing that works is the wild encounters after the starters choice. thanks for any people that can help me

(sorry i use google trad)

[drifted]

i havent seen anyone else mention this so it may just be a me problem but pk3ds refuses to let me rebuild my exeFS and romFS, in every way possible

 

it dosent even TRY to give me hope when i rebuild them as a patch, instead it just gives me this error - regardless of how many or how few options i have ticked on the left

 

its extremely annoying and im wondering what im meant to do to fix it? the error message isnt the most clear to say the least

 

this is ultra sun btw, and i havent randomised anything, but i have edited text and pokemon stats (and moves)

The error message tells you why it was unable to continue, you did not give it a full ROM dump to work with. It is looking for a "rom2" path for the exefs, but no file was found, and it cannot patch the exefs for your modified files.

Current advice is to use layeredfs via custom firmware, instead of rebuilding ROM files.

[Maikikii]

Hello!
I have a question. With PK3DS can I insert an NPC that gives Rare Candy to the player, or have them already appear in the backpack/PC by default? this in Pokemon Omega Ruby

No, this program does not support adding NPC, nor does it support editing scripts.

Oh, I understand u.u Do you know any program with which I can do something like that?

Hello!, another question. Is it possible to include OR Version 1.4 in Pk3DS?

no, you have to use the base game version of your rom

so i tried that, i put both the exefs and romfs folders inside luma/titles/0004000000164800 (i switched to editing pokemon sun bc it would be easier) and whenever i enabled game patching with the latest version of layeredfs and tried to load pokemon sun, both of the games screens would turn grey after the game took abt a year to load.

 

not exactly sure why that happened, apparently it was an arm11 core (1) exception prefetch abort (svcBreak) but nowhere online seems to be having the same issue as me

im able to restore the game back to normal if i put the unmodified romfs and exefs (and everything else) into luma/titles/0004000000164800 and repatch pokemon sun so i know its just an issue with those files, but im too stupid to know what that issue is

 

i can send a photo of the arm 11 exception error message if need be obviously

edit: i didnt realise im meant to rebuild the romfs and exefs in pk3ds holy fish i need shot in the forehead no wonder that never worked before, ill try the rebuilt romfs and exefs to see if they work instead, my bad for being such a moron

Edited May 5 by drifted
being moronic

[drifted]

okay now i have an actual question to ask that isnt routed in me being fundamentally stupid

is this message telling me to NOT use layeredfs to get the CROs and CRR working on my 3ds otherwise it'll fail the RSA check? do i need to install smth else on my 3ds to get these files to work properly? or should i not bother and stfu

Modern CFW (luma) has this patched by default.

[drifted]

somehow managed to fish up the evolution editor as well, crashes pk3ds entirely after i close the error message it give me whenever i try to open the evolution editor, stating that "item" cant be null

im assuming that means that ive changed a pokemon to evolve with an item being used, but never said what item, so that causes the crash? can i edit the romfs manually somehow to circumvent ts?
