Yu-Gi-Oh! 5D problem

Hi guys.
I didn't want to spam, but I've looked trough forum and didn't find subject, and I didn't want to start new thread...The thing is, I've downloaded YGO! 5D's WC 2009, but I cannot run it.
I'm using no$gba, I had no problems with YGO! WC 2008, but with this game I'm getting "Unable to read data. Please turn off the power and reinsert the game card."Help any1?

I'm not specialist[well, I suck, honestly], but I think that you gave me good tutorial for consoles...
I am using Emulator, so correct me if I'm wrong, but that's rather useless...And if anything, please give me some explanation on these flashcarts [only if they're connected with emulators]I'd be gratefull

"EMULATOR: Go to the Emulation Settings, and change NDS backup save media accordingly, and reset, until you do not receive the errors. If you want it a bit easier, you can get no$gba 2.6a, which has a Auto option, which automatically chooses the right type according to the game, which makes a lot more easier. If this method does not work, simply wait for a new release of the emulator you are using, or resort to using another emulator for the time being (iDeaS etc.)"did you even read it?

Replying to #4

Yeah, then I've noticed that I've downloaded no$gba v 2,6 as 2,6a[honestly why people are uploading things like that[it was form polish site]], anyway, now I've got another problem - game [emulator] does not see save files...
Ideas?

What do you mean? Any error?

thank you .
