Thank you Very much Ben!!! you really know your stuff!!! Thank you!
as for the guy with mircrophone problem here a pic of were it should be placed.
eh..might of messed up with links but it should show were the mic shuold go on the new ds case. unless iam wrong and misunderstood, thats were it should be. also make sure for this inexperinced person that make sure the rubber thing doesn't cover the real mic. i put mines under the screens metal end, which i did on my own acourd, not sure if thats the right way but its fine with me. hope this helps
