Don't know how to do the paper trick, but I doubt it'd work. Occasionally, my DS has a hard time recognizing my R4. It takes sixteen tries to get my R4 to be found in my DS. When it does find it, It usually freezes five to ten seconds after loading a game, then when I turn it off and back on it can't find the R4. Usually if I take it out and put it back in after that, it works well. This only happens if I don't play it for an hour or more. If I keep the DS on and play a game for a while, turn the DS off, then back on in the same hour, it'll work.. But if I turn off the DS and wait an hour or more, then try to use the R4 again, I have to keep ejecting the cart and putting the cart back in a bunch of times before it can be recognized. Help? The last time it did this, the Micro SD was corrupted and had to be reformatted. After it was formatted, it worked great and it was recognized each time I turned the DS on, but that's slowly went back to shit.
