Well, I use the American version of Pokemon Platinum when making this patch, so I assume this patch will only work for the american version rom.
That's the AP, in order to get passed that, you need to download the
Rudolph's patch. You can find that on Gbatemp.
If you're using emulator
To be more specific if you're using No$gba or desmume.
For no$gba you need the use it with the No$zoomer Extension. With No$gba bios, I forgot to add that last time I was talking about No$gba.
If have desmume, you can run it perfectly by just patching the rudolph's patch; I don't use desmume, because my computer's too slow. It'll probably work differently on yours
I'm using no$gba with No$zoomer
nvm, i found it.
