What do you mean by bumps?ShadowSoldier said:He just told me, that under his sticker, there are bumps. And there noticeable by eye. And I look at mine, and you can't see anything. Could he have gotten a messed up card or something?
If there is a square shape under the sticker bump under the sticker then it's normally a clone. If he means there are bubbles or air bumps, then it's just from where someone has put the sticker on. These arrive stickerless to retailers, and someone has to put them on manually. If someone has put the sticker on wrong then removed it and put it back on properly, you'll see a few bumps.
Most Acekard 2's will have a slight bump in the middle from the blob chip underneath. It's nothing to worry about.
As I've said in the guide already linked to, some people are having troubles with them on DSi XL's.
"Try placing the XL on a stable flat surface, without moving it power on the XL and boot the acekard. Don't touch the touchscreen, just leave the game running through it's intro for 15mins. If it's still working, pick it up and try using the touchscreen; if it then hangs it's a contact issue. The movment will be causing the Acekard to move slightly in the slot, as will pushing the stylus against the touchscreen.
"A few people have had similar problems on their DSi XL and have solved it inserting the Acekard into the XL's slot normally until it's locked. Then without depressing it, pulling it out slightly; you shouldn't be able to pull it much because it should be locked."
