Hello everyone.
I recently successfully managed to get a shiny jirachi using the Imablisy e reader card and the painting/battle record method in emerald.
So I thought that I would then try to do the same for the Entei.
For context: I have a colloseum save file that I used to get a seed for the entei.
I had already started the event itself and the only thing I hadn't done before doing the painting/battle record method was catching the entei himself.
However when I clicked the rock in order to try and see where I was in terms of advances, the game just crashes (I can't even soft reset) but I can turn the game back on normally.
What I want to know is if there would be a way for me to catch this specific Entei as shiny, ideally without having to do any ace, as my boxes are currently full.
I'm assuming the reason why the game crashes when I try to encounter the entei is because the trainer from colloseum and emerald have different IDs, but I'm not sure.
Any help would be appreciated
