pk3DS: Pokémon 3DS ROM Editor and Randomizer

Maikikii · July 5

Hello!
I have a question.
I am going to make 32 Pokemon ORAS roms, in each of these I will modify specific things, for example, gym leaders and rivals.
My question is, is there a way to create them "quickly"?
Currently I must randomize all the trainers first, then I modify each gym leader manually. But, as you can imagine, this takes time and when doing them for the 32 roms it will be a long time.
I do this so that the randomization continues to be maintained and each rom is different, except for things like these combats or mega evolution abilities.
I see that in the "Tools" tab, there is an option that says "Set int32 seed", but I don't know if this function is for that, and if it is. How can I create the seed?

Hey, I'm trying to remove the shiny lock for ORAS, and when I try to put the folder with the exefs and the romfs into pk3ds, it shows an error message that says, "File count does not match expected game count. Files: 1101"

I'm pretty sure I've done everything right. I've renamed .code to .code.bin as well. How can I fix this?

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.

I really do need an answer to that question too, because I have the exact same problem and I don't have a clue on how to fix it...
