So I bought a 3in1 for my ds lite about 1 & A half years ago & I stoped using it since about 6 months. Now when I opened it I started having some trouble. When I open exploader it says that it isnt set to use it every time & all games I open fail to save ( not save then later disappear it just says something like "save failed"). I then thought it might be the battery dead so I went & bought me a new battery and replaced it. So now I was wondering if this is really battery related and I messed something while replacing it or did the sram die and I need a new one.
