Help needed. Data abort crash while playing randomized & arm9 edited Gen 4 & 5 Pokemon games

[Valdihr]

Hello!

Recently I've been trying to play some Randomized Shiny Nuzlockes in Pokemon Gen 4 & 5 games but I constantly get these red data abort crash screens which makes them unplayable.

This is the ROM hacking process I use:

-Use CrystalTile to extract/export the arm9.bin file.

-Use HXD on arm9.bin to edit the shiny odds values (using this tutorial: https://projectpokemon.org/home/forums/topic/62440-pokemon-hgss-gen-5-games-new-way-to-modify-shiny-odds-1-100/)

-Compress/Import the edited arm9 back into the rom.

-Use Universal Pokemon Randomizer to randomize starters, wild encounters, wild and pick up items, text speed.

 

I tried it with HeartGold, SoulSilver, Platinum and Black and each with ROMs from different sources. All of them crash the same. The crash occurs both when I play the games inside Twilight Menu and from the homescreen after using NDS Forwarder, makes no difference.

Anyone have any idea how to make this work?
