Help me please. What is the cause of this problem, and can I fix it? I am using Ds lite and supercard dsone. Until recently, I used microsd sdhc 32gb and now I switched to micro sdxc 64gb. And using the same version of gbarunner, some games do not run on 64gb when they run on 32gb! Batman begins, Ultimate spider-man, Naruto ninja council 2. Why so? I want to use a 64gb card and compile a complete collection of what interests me and what works on my Ds lite. Please help.
