Okay, my story is a distressing one, perhaps. Just bought my DS on Saturday only to realise four days later there was a line appearing on the upper screen and after referring to Nintendo's official website, it's a hardware problem. I had to send the DS to Nintendo (via retailer) on Wednesday. So now I have an R4 and I want to play Pokemon Diamond while waiting for my DS. Are there any emulators that can play Pokemon Diamond at full speed and the saves work on my R4 so I can continue playing on my DS after I get it back?
