So my good ole DS lite decided to finally crack after 4 years. The plastic where the hinge is fell off. I'm planning doing a full shell replacement but is it recommended that I get a new hinge as well? It doesn't hold the upper like it use to anymore but that could be because of the part that fell off. This would be my first time taking apart a console, so if I follow the instructions to the dot, I should be fine, right? Also thinking of replacing the battery as well.
