Whenever I try to start it up I just get a black screen. At first I thought had downloaded the wrong version of the cart's software, but even after deleting the directory I got the same blank screen. Is there any way to fix this? I couldn't find a miniSD literally anywhere on the internet so I'm using a 4gb microSD-hc with a miniSD adapter. Is the Adapter what's causing the problem? Also if it matters, I'm trying to use cart to play gba games. I tested it out on a GBA sp and a DS lite (same results).
