Dual Slot recognition problem in Pokemon Platinum?

Alright, so I have a .nds rom of Pokemon Platinum that I downloaded from here onto my R4 cartridge. It was the english version and was patched a few months ago (I think). I was attempting to use the "Dongle" method, which basically requires an old GBA Pokemon game in the the second slot of the DS to unlock bonuses. I have some real GBA games I bought for cheap, however it the game doesn't recognize that they're there.Is there a patch or something I can do to fix this problem? You know, so it finds the game there? Or can I download the gba game to my R4 cartridge and do something, or what?

i have the same problem

me too... and the file on the gba cart got geleted...

So anybody know anything? I've googled it and came up with nothing.

No, because you're using ROM. There may be a patch for it, but I wouldn't know.

From what i know, it's a region locked feature.So : if you use the US pkm platinium you must use US gba version (French version with french gba version and so on) US and UK version are 2 distincts versions. Maybe that's your problem ?

I think it's a compatibility issue with the flashcart. I remember reading similar stuff in the release notes of updated firmware for some flashcarts. It likely works with some flashcarts, but not with others.And I don't know a fix/workaround for this issue either :(

Alright, well I'm using the same region for the games so that eliminates that. But I'm thinking it may indeed be just a compatibility issue with my flashcart. So I'm going to see if there are any updates from where I got it or anything like the like.
