I use Nintendo-DS-Cases for the most of my loose NGPC-Games
...for me thats the perfect way to store them.
I downloaded the Inserts from thecoverproject.net...and made some on my own...
Modding a NGPC is a pain in the ass. Its extremly hard to make it without getting dust inside...
Im really satisfied with my modded NGPC wich was made by a German Modder...
But no one should expext a miracle...frontlights are just not that sexy then backlights...(love my 101SP modded usual Game...
