I've already tried the paper trick with my dstwo, and I saw the bad batch thing,and I had mine wait and let the company get a new batch of cards before I got mine shipped to be doubly safe. It has worked perfectly on my ds lite, dsi and blue 3ds. This one appears to be dropepd as it's got a chip on the bottom of it, and when I got it, it was kinda finnicky but then worked fine after awhile but now it's refusing to do it. The 3ds blue card has no guiders, whereas the dstwo has all but ~9 of the ones of a retail card and refuses to run on it.
And yeah the gateway blue card has no guiders for the pins on it, so that can definitely be seen by me, but since it's just that one that refuses to run it's got me confused. My dstwo does take a little bit to load(because I have 4.5 and thus the 3ds is doing more checks and it takes longer for the card to complete the fooling) but this one doesn't do it at all which makes me confused as all get out.
Edit: OK so after trying to do it over and over again. And then finding the thickest paper that I can find and continually pushing more into it. It's now working. So the pins are bent.
The paper trick half works, it takes a lot of working with it to try to get it to fully get into it. And it's more a case of guessing what to do than a real science. I wish that flash carts would've used more guiding pins on their cards as it can't cost very much to include them.
OK so trying the paper trick again, I can get it to read the dstwo/blue card but the white card won't do it. this whole thing is making my head hurt as to why the hell it won't just work even with paper behind it. I can't put anymore behind the label as it won't fit and yet it refuses to show up.
Edit: OK the paper trick kinda works, it works with the dstwo, and the blue-card but the gray card refuses to show itself. I don't know if this is something weird with the card itself as I don't know why it's not wanting to run it. So it is bent pins.
