Okay, so I was having problems with my R4 being detected by my DS. I finally gave in and tried the paper trick. It works WONDERS. I haven't seen my R4 work this good since I first got it. But I have a question. Last time I couldn't get my R4 to be detected so much, I ended up having to reformat my Micro SD card out of frustration. After that, it worked 100% well. The R4 was detected 100% of the time after that... But that detection percent began going downhill after a while. Why did that fix my detection problems as well as the paper trick?
